Why I almost stopped using Royal Purple

My experience with Royal Purple destroying an engine, my discovery as to why it did, and the reason I still use Royal Purple

[@mystikflight]

In all my vehicles from bikes to cars only Royal purple is used. I've been using it for more than 30 years and never a problem.

[@caseysgarage5991]

+mystikflight Harley told me that they would void my warranty if I use it in my bike, but it's in every other engine I own down to the lawnmower! Thanks for watching!

[@mystikflight]

Casey's Garage I put Mobil one in my 2003 883 hugger no issues. Synthetic oil in most major brands is a win win. Oil break down no issues especially in small engines

[@caseysgarage5991]

mystikflight you hit the nail on the head there, synthetic oil is so good anymore, you really can't go wrong no matter what you happen to use

[@jackpalance9509]

Second owner of a 99 Frontier with 56,000 miles on it. 4 cyl.auto single cab. Now, normally I use whatever oil is on sale but I am trying to see if perhaps it can help me squeeze out some more mpg's. Getting around 20 with non-ethanol gasoline which I prefer. I'll let you know the verdict.

[@berniediapersanderslukso9204]

That is one of the best oils out there. It wasn't the oil that damaged your engine it was the sludge.

[@caseysgarage5991]

Should have animated the glove box door to the words so this picture would make sense.

Great story. It shows that the detergents in Royal Purple works excellently to dissolve the sludge. I've been curious about Royal Purple, I definitely want to give it a shot. I use Valvoline Syn Power.

[@MrGarteck]

Te recomiendo Royal Purple , la linea HPS¡

[@renzokata]

Ran my car really rough trying to install a throttle body, idled at 4000rpm for a while and became worried about the engine. Sounded scratchy. So I switched from synthetic to Royal Purple. She's running smooth now. Royal Purple is good stuff. Yeah, sometimes sadly, the grime and stuff in your engine, sometimes holds old seals together and what not... A lot of people have this problem when they suddely switch to synthetic.

[@mannylumbres520]

I have a 2000 sienna with 375k. Supertech HM Syn blend for most of those miles. No leaks or funny noises. Eats about 1\2 a qt every 500-700 miles. I put royal purple in it once and it developed a noticeable tick. Drained it after a few drives and refilled with Supertech. Noise disappeared after 2 start ups.

[@sportsmansparadice42]

Pennzoil platinum for me. The guy's from Hennessy swear by it. Its factory fill in Ferrari. If it's good enough for a 788 horsepower Ferrari 812, and 1,000 horsepower Corvette ZR1 it's good enough for me.

Best advice that I could give anyone is to run Royal Purple or Mobil 1 oil in their car or truck depending on what kind of vehicle they have and only go 5,000 miles don't over do it buy going 15,000 miles because you will get engine sludge especially if you drive a lot in stop and go traffic and especially if you have a truck(Any Chevy 2001-2014 with a 5.3 or a 4.8 & Ram 2000-2016 1500 and up) change your oil more frequently it will save you money in the long run trust me i have a 2005 chevy tahoe LT 5.3 bought at 140,000 miles and only used mobile 1 but after ever oil change only running it about 2,800 miles it was 1qt always low and I know these types of chevy with higher miles are notorious for burning oil but for about a year this happened and 4 oil changes a year and I have no oil leaks what so ever and only driving it about 10,000 miles in the first year I purchase (Mobile 1 just didn't do well in my tahoe so I'm not knocking the brand down because I also have a 2006 lexus gs430 with 128,000 that I still use mobile 1 in) so then i switch to RP at the being of this year and I only do 2 oil changes a year now 2nd one I just did a week ago and noticed I'm not topping it off with oil like I did with mobile 1.. So again to me just put in your vehicle what you feel makes your car or truck run better just whatever you use make sure to check your oil level 1 time a month and change your oil more regularly then 10 and 15,000 with a vehicle with 90+ thousand miles if you want it to last and not have high repair cost.. Hope it helps

[@joes.7536]

The new 0w 40 European blends are the best thing out for any car right now. Superior hot and cold protection. I run it in a 1.8t Volkswagen and a ecoboost Ford escape. Motul 8100 or Castrol edge euro. I wouldn't hesitate to run Royal purple as long as it meets VW 502.00 spec. I've ran it before in 5w30 and had no issues. Turbocharged motors have high oil demands. Lots of heat produced. Conventionals sludge up.

[@brianhollister460]

I switched to Royal purple @52k in my Toyota. At 55k miles I had to put a new engine in it......most expensive oil change of my life.

I've used royal purple twice, in my civic and BMW. Both cars run so smooth and so quiet. It kind of scares me when my engine is running bc it's so quiet that it me makes me think my engine is off. Engine will definitely feel it's running more freely with less resistance. I've used many different synthetics, and no one comes close. I can say it's the best oil I've experienced so far. The down side about royal purple is the price, too expensive !!

my car makes valve lash noises after using hyundai xteer fully syntethic oil. Its a 225,200 km old car. What the oil does is cleaning sludges off the lashes. It prompted me to buy a brand new valve lashes.

[@righteousredneck777]

Im sure liquid Barney works fine, but Im sticking to Castrol Edge.

[@gokartbuyer]

Paying for purple dye... I don't care what color the oil is going in as long as it comes out nice and dark. Castrol and mobile1 came out pretty clean when I changed the oil in my old Toyota. Pennzoil did a far better job cleaning and the oil pressure gauge sat a bit higher with it.

Is it save to use royal purple on my mazda 3 2007 with 148000 miles? I use moble 1 high miles

[@caseysgarage5991]

If you change oils, you must use high mileage oil, regardless of the brand. High mileage oil has additives to swell your seals, and stopping using high mileage oil will cause a leak

good video. somefhing to think about !!!! I have a 2002 Chey Avalanche, 240 000 km On it. I have owned it for 4 years and have always used Valvoline synthetic 5w30. I live in North east Canada and it gets cold in the winter. -20 to -30. Fot this reason i was thinking about going to 0w30. I know its still a w30 oil but was worried about the oil being to thin and posibly leaking, Maybe if i did half 5w30 and half 0w30 it wold make a 2.5w30 LOL

[@caseysgarage5991]

I wouldn't worry too much about going from 5w30 to 0w30 in extreme cold, it'll be thicker on start up and the correct viscosity at operating temp. Probably wouldn't do it during the summer months though

[@elonmusk8667]

A quart of Royal purple is worth more than the car here.

Is it purple? I heard it was. Also heard its not sn certified? Is it? Api sn resource conserving?

[@caseysgarage5991]

It is purple. It's also sn certified. It's also GM certified for the latest generation of GM products, which is the building blocks for the new API sn+ certification, which is mostly for turbocharged engines, but it should pass that certification

So at what Mileage point is it to late to change to royal purple. On your point of view. I have Jeep with 77k & after watching your video I want to change over but Not sure yet.

[@caseysgarage5991]

I would say that really depends on your car. If it's been beat up and neglected, it might be an issue, but if it's well taken care of, you're probably fine under 100k or so

[@caseysgarage5991]

Maybe look under the valve covers for sludge before making a decision

[@sinformant]

Casey's Garage weird. I used to run royal purple in my civic si and ran that car hard every 3,000k miles I changed it, it came out purple and barely even darker than it went in. My current car I run Mobil 1 in which is what it came from the factory with I think its a good oil but it comes out black as a cloudy moonless night when I change it. I'm sure the fact that it runs through a hot turbocharger has something to do with that

[@normanheen9691]

I have always use Pennzoil since I was 16 years old I have never experienced an engine problem related to the lubricating oil I think a lot of the other products or just advertising hype these improvements and synthetics aren't really totally necessary unless you're driving a turbocharged or supercharged engine regular passenger car engine regular if you add a quart of Marvel Mystery Oil was it because that prevents sludge formation and clean the inside of the engine

[@caseysgarage5991]

+Norman Heen anymore, no matter what engine oil you use, you should be using synthetic oil. Remember that engine tolerances are much tighter than they used to be, and compression ratio is higher even in a naturally asperated engine than before. Thanks for watching

[@caseysgarage5991]

+Norman Heen glad to hear it! Your engine will thank you for upgrading your oil, and I hear great things about that oil. Apparently natural gas is a great base oil

[@jeffersongraves5295]

I usually run royal purple in everything besides my lawn mower. Only vehicle I didn't run rp in was my 84 Chevy dually with the 454. Reason being is that with the age of the engine and type I thought it would be best to try the Quaker State 50/50 recycled oil. Great oil in that engine but everything else gets rp because I've been using it almost 15 years and was getting 12k mile intervals years before it was advertised. I also use rp in my ar, makes cleanup a breeze and sucks the carbon of the metal

Being a long time mechanic of 50 years I’ve learned a little along the way and use nothing but amsoil I feel it’s the best oil out there along with schaffaer which is just as good Mobil 1 is ok but way overrated and royal purple I tried with bad results along with some people I knew that used rp and had disastrous results so use what you want if you change oil regularly with filter that helps big time but if you want your engine to last long time use amsoil or shaffaer

[@MasterChief-sl9ro]

can you read a bottle of oil? It says change your oil per manufacturers owners manual. That means read the normal service conditions. Then the one under "extreme" conditions. Hell you didn't even know. Putting Synthetic in an old beater was asking for trouble. As it all that cheap oil over the years makes seals\gaskets hard. Not to mention carbon buildup is what is holding all the oil back from passing your rings and valve seals. So word to be wiser. Pull a damn valve cover off. If it's black. Don't even try and use synthetic. You will find every leak in your engine real fast! Been there and done that. As pulling an engine and replacing all those Seals. Rings and Gaskets is not fun. Unless you're getting paid for it!

Their Synchro Max trans fluid did wonders for my manual transmission as well.

[@TNsher776]

I've heard this same testimony from another youtuber about royal purple, I use royal purple in my 2015 Toyota Tacoma for over a year now and never had a single problem with it! I change the oil every 10,000 and the oil stays at the exact level on the dipstick as the day I poured the oil in the engine, no oil burning whatsoever! The Tacoma has a 4.0 liter V6 in it, engine runs smooth and water temperature stays cooler than other oils in the motor! The truck has 49,000 miles on it, I plan on using royal purple 5W-30 oil in it for as long I own the truck! I hope I'm making a good decision doing this! I plan on driving the truck many years, at least for the next 10 years!

[@justinfincher2385]

You’re absolutely right, the sludge and varnish seeps into the seals, and once you put something in (most synthetic oil) it will remove the sludge and varnish, and in turn can dissolve parts of your seals creating leaks. Royal purple is fantastic, I use it in everything, all of my fluids are royal purple including my diff fluids. I love it. But it wasn’t without trial and error. My 97 Chevy started leaking like a dog stuck inside after switching. I had to replace the oil cooler lines and all that fun stuff because the royal purple are the sludge. But when you opened the oil cap you could look down under the valve cover and on this quarter million mile truck that had pennzoil run in it most of its life, the rockers and valve springs looked brand new, whereas they used to be covered in sandy looking sludge. Also I went from 11mpg to 15 in that old Z71 suburban. Well worth the extra cost.

[@dfls5069]

Worth the cost how? You just said you had leaks after switching to RP synthetic

[@scubbarookie]

I know that RP is one of the best sludge removers on the market! My 99 4Runner has over 328, 800 miles and pulling strong!

[@andrewtrask9650]

Thays what alot of people do that switch to royal purple because it cleans so well put it in for 500 miles then change again and you will be shocked how much sludge is in you engine

[@ShovelMonkey]

After I did my cam break-in with the Lunati break-in oil on my Lunati 10200701 hydraulic flat tappet cam in my 68 barracuda with a little 318, I only run Royal Purple HPS 20w50. I developed a rear mainseal leak due to the fact that the seal was forty-six or so years old and the old dino-oil sludge acted as a seal. The synthetic oil cleans out all that old sludge, as Casey's Garage discussed. The fault lies with dino-oil hiding, or covering up potential problems that need to be fixed anyways. I run a 195* thermostat to keep temps high enough to eliminate/evaporate the water that is a combustion byproduct and gets past the rings from building up in the pan. I do _NOT_ run an oil cooler for the engine. With my new 727 transmission, I run a B&M oil cooler, in addition to the cooling that is done by the radiator. I use Royal Purple ATF. The only reason that I'm using Lucas gear oil instead of Royal Purple in my Dana 60 is because it came from Strange with it. With my (new) 1991 360LA engine build, I will also be running Royal Purple, whether I go with a hydraulic roller cam, or a solid flat tappet cam. Keep your build clean, pay attention to clearances, seals, rings, torque specs, et cetera and you will be fine. Remember to use the appropriate oil for your cam.

[@caseysgarage5991]

Thanks for the information, it's great to see people that understand the cause and effect of things rather than blame the last thing for something

[@TNsher776]

I think royal purple works best in engines with close tolerances in bearing and piston spaces! Due to the oil being so thin! If you have bad piston rings, you'll burn more oil with royal purple than other oils. May try using a thicker viscosity royal purple oil, like 10W-40 or 15W-50

I run Royal Purple in my RX8. 7 years I have owned it. Not a single issue with it either. The oil almost never comes out purple though. It stays pretty clean for about 1500 miles or so, but by the time I hit the 3000 mile mark and change it, it's pretty dark. But, rotary engines run pretty hot. So, that may be part of it.

As far as performance goes, I’ve never used anything other than Royal Purple so I wouldn’t know. What I will say is that I’ve got a lead foot, and the 305 my Elky had overheated and started the next day, and the 5.9 Magnum that my Ram has is reliable in every way except fuel efficiency. I will never use anything else.

+Angel Estrada like I said, it works great in my other engines, that one in my old truck was just too old and worn out. Thanks for watching

[@dnawrapsatl]

What car do you use it in

[@44hawk28]

About 4 to 5 oz of Blue Devil seal conditioner / stop leak, along with a bottle of cd2 would have probably help the seals quite a bit and kept that motor running for as long as the motor would have liked to run. Remember the Blue Seal Oil Stop is very aggressive and has to be used any no more than a ounce per quart.

[@caseysgarage5991]

High mileage oil also has seal swelling agents to prevent leaks. As I said, that particular truck was an old farm truck, and it worked hard until the end of it's time. 200,000 miles is nothing to laugh at in those surcomstances. Thanks for watching

[@slingo182]

1 got a 03 Saab whith 140k miles and changed the oil to royal purple a week after I purchased it, two days later the motor just took a shit and would just spin whith no compression while trying to start it. Fuck Saab

[@Jon-O.]

I want to make sure everyone understands that when you take an engine that may have not been properly maintained. Or only had conventional oil used in it. With synthetics and I can't stress this enough true all synthetic oil that's 100% synthetic. This oil removes varnish and sludge buildups and keeps it emulsified so that the filter can actually get pick it up but then it also reveals what the conventional oil did and that's premature wear out of your engine in respect to valve guides seats cam bearings crank bearings piston pins and the like. But true 100% synthetics like Amsoil have the highest film strength at 188,000 lbs per square inch. Above all other synthetic oils on the market. That film strength also helps fill the gaps in the wear out as long as it's not excessive. And remember your labeling of your oil if it says full synthetic that does not mean it's 100% synthetic. In the court case between Castrol and Mobil 1 the judge decided that any petroleum oil that contains a minimum of 25% the synthetic content can be labeled as a full synthetic. So unless the oil specifically says 100% synthetic or manufactured from group 4 or group 5 p a o or Esther's it's not 100% synthetic. So if you're going to pay the high dollar for the high quality synthetic oil you might as well go with the 100% true synthetic. Do your homework and don't be ignorant and just believe what a label says. The petroleum companies have been ripping consumers off for too many years don't let him do it to you. Also very important here Amsoil was the first true 100% synthetic oil certified by the American petroleum institute. Check this out from project farm kzbin.info/www/bejne/e2PdhGuDrtt9rrc

[@enriqueortiz5440]

If you have a high mileage car and have been using conventional oil, DO NOT switch to Royal Purple Synthetic. It cleans away gunk and deposits in you engine and that gunk is most likely the only reason your car or truck didn't burn oil. If you have always used synthetic or your car is very new/highly maintained you should be ok.

[@MrPsiclone666]

this is gospel. if it has built up sludge from the dino oil over the years you dont want to go full synth. stick to dino and keep the engine happy..

[@Jon-O.]

So false a wives tail no evidence to back it up. True synthetics break down buildup from use of conventional. This is why Amsoil stresses a engine flush before installing a 100% synthetic like Amsoil signature series. Unlike royal purple that is not 100% synthetic.

[@alexpatron3024]

I used Mobil 1 in my '85 Corolla and it went 394000 miles. So far my RAV4 has 245000 and the engine is still going strong.

[@caseysgarage5991]

That's great, hopefully you hit 400k this time

[@witnesszer0]

i think that royal purple let your buildup free and clog your oil filter

I used Amsoil signature oil 5 times. On last oil change I developed a lifter tap. My store was out of Amsoil 10w30 signature series so I ended up with Royal purple 10w30. Lifter tap went away. 1999 Pontiac firebird v6 3.8 148,000 miles. Runs really good and still gets great gas mileage. I would run Amsoil again but it is hard to find locally.

Royal purple is a high performance engine oil made for muscle cars and race cars and can be used on new cars and trucks the average daily driver that hasn't been super babied or taken care of very well would be better to use valvoline high mileage synthetic it's made for cars and trucks with over 75,000 miles just my opinion using royal purple on a old car or truck that hasn't had it's whole life is a big waste of money any engine oil used on a old engine is not going to make anything run better and if it does it's in your mind don't change brands change it often is best clean is better every 3000 or 6 months don't care what manufacturers say 15,000 miles or one year is bullshit

[@myballzizitchy3173]

My suggestion for owners of high mileage vehicles is that if you decide to use Royal Purple then after using it the first time you should change the oil again after 500 to 1,000 miles. Get the sludge and dirt that it has cleaned out of the engine and put fresh Royal Purple oil back in. I've done this and had zero issues with a Jeep Wrangler with over 200 thousand miles on it and it runs like new with no leaks and doesn't burn oil at all.

I run Castrol because it's not a matter of brand but of certification (API and/or JASO). As long as it's what's required on your owner's manual you're good to go. All synthetic oils are good for street use (even the cheap stuff if it's certified).

[@caseysgarage5991]

Absolutely, even the worst full synthetic oil is better than the best conventional oil, so long as it meets your engine's requirements

I won't touch gucci oils. Chevron Havoline Pro DS is all I ever fit in my Subaru Forester XT. Flies under the radar but an extremely good oil 💪

[@tommy35ss]

They make a high mileage oil now days, it has seal conditioners in it. Probably for this exact reason. Sorry to hear that happened. I rolled my Jeep in Moab last August, running Royal Purple 5w-30 HPS, and had to crank it with no oil for about a minute, when being winched out. The Jeep made it and did not sieze up, nor does it have any wear that I've detected so far from the incident. Still no burning of oil either.

A lot of life left in that engine, I would trust it on a 1000 mile road trip as it never let me down

[@jamesj.litteriojr.433]

Royal Purple is an awesome oil and does clean like nothing I've seen before!!! Gets rid of some noises, engine runs way smoother, etc. I run the HPS version because my car is out of warranty and as long as you are not burning any oil, it won't damage your catalytic converter at all even with twice the zinc it has...1600ppm vs 800 ppm for warranty issues.

Expeirenced the same situation on my 04 Town&Country 3.3 with well over 200 thousand miles, engine made a hellacious noise after about 500 miles of running RP, then it started smoking BAD and had tons of oil under the front of van. Changed out oil again with fresh RP, and a #KNoilfilter, oil was BLACKER THAN BLACK as it cleaned out sludge build up. This time I added a bottle of #STP High Milage oil treatment with STOP LEAK, zero issues going forwad. No oil leaks, no smoking, no engine noise, improved gas mileage, more power, longer oil change intervals & my engine ran cooler!! 💯 I'm sold on #RoyalPurple!

[@Quis85]

I know this is old video post but I just started using RP. I had oil leaks like crazy. I replace rear main seal and recently value cover gasket. And pressure washed the engine now that i have a new value cover gasket and manifold gasket. I already knew to wait to use RP being I already had leaks. Lol. Now I'm happy and can't wait to change oil again to see all the garnish and etc just slide out from RP cleaning the engine and doing its job. The pep boys manager was like damn never seen a 06 hummer 200 000 miles look this good. Even though it was leaking oil. Now I know its going to ride so much better now. As well as I've already seen difference in temp. So I'm sold on RP

[@gabrielcastillo4606]

I’ve always wanted to use Royal Purple in my cars but I could never justify the price over other products. I’ve always done oil changes before they were due. I just bought a new Chevy Silverado & a few months later a speed sensor went out & the truck would sometimes shift hard or not shift into overdrive. Sometimes there wasn’t any throttle response. So I decided I needed a transmission fluid upgrade. Just started using Royal Purple & changed out the speed sensor as well. Shifts like a dream!!

[@caseysgarage5991]

Having a protective film in case of emergency is a great thing, but keep in mind that engine oil does so much more than just lubricate. Engine oil is the first place that heat gets transferred to, and so running without engine oil will cause hot spots in the engine fast. Keep in mind that I am in no way recommending running an engine without oil, I'm saying that in the event of an oil leak, Royal Purple makes it so that you don't have to rebuild your engine.
