Harley-Davidson Oil is What You Should Be Using

[@GixxerFoo]

What is your trusted brand of oil that you prefer to use?

[@trex860]

H-D Full Synthetic

[@devimead750]

In England I use Morris Lubricants, Ring Free XHD40 monograde engine oil in my 2000 88B Twin Cam, I have done ever since the first 500 mile HD oil change. I buy their oil in 25 litre drums so that I never have any trouble with supply. The bike has now done over 53,000 trouble free miles and doesn't burn a drop.

[@straightener2001]

I used to use Harley mineral based lubes. After tearing into my last bike I quit using it. I bought the bike used with 60k on it and the tranny was junk. Had regular maintenance, I have documentation. Transmission gears had a burr on the edges, clearly lubricant failure. I use Lucas synthetics now for everything along with Wix oil filter (another can of worms there).

[@MeanOldBastardBikerBob]

Bikes that use same oil for engine and gears will really tell the quality of the oil ,gears will shift silky smooooth.,,vs hard clunk..ie MX ,hondas ,vrod,..Iv used amsoil in my sleds for years 2 strokes ..In my big bike$ I use amsoil #1..RMZs, DRZ Castrol from CANADAIN TIRES . worst oil for my money I feel ROYAL PURPLE 👎... trucks /tractors and cars by the pail for walmart ,, change regular 5000km ...

[@tonyc2912]

I just use HD Syn-3 and HD gear oil for primary and transmission. This has served me well in all of my bikes. I ride across country a lot, and all I need to do when changing oil on long trips is to stop by any HD dealer and Syn-3 will always be on the shelf. I usually dump oil at 3K miles, so not worried about 5 or 10K oil changes. Living in Florida, I ride 12 months out of the year and daily ride on my bikes, including very hot summers. No issues with HD products. Thanks, and ride safe.

I did some work on my primary and filled it up with John Deere hygaurd oil because that’s what I had on hand. Very pleased with the clutch feel and looks good after 5000miles!

I just bought the 2022 Harley Davidson Nightster and I use Motul 7100 full synthetic oil. It is Harley approved and the Harley mechanic fully endorsed this oil. I used it in my Ducati Monster and I loved it and so does my Nightster.

[@PeglegPPG]

Amsoil is far superior for all three holes and is easier on the pocket! I went from all Harley fluids to Amsoil and my trans shifts better without the loud noise

[@FeatheredDino]

I prefer Redline, personally. I've had better results with it. Started using it in my Challenger R/T and it quieted the normal valvetrain noise, and dropped my oil temp by about 12 degrees. That is proof enough to me. If it does that in my car, it'll work miracles in my Harley -- and it absolutely made the normal Harley valvetrain noise more quiet! Edit: I should note, if and when I don't feel like ordering Redline and waiting for it to ship to my house, I'll substitute it with Castrol. When I can't get Castrol I'll use Mobil 1, because it's good stuff, and it's everywhere.

I asked the tech at my local dealer. His advice was Amsoil blended for each hole. I change it myself. I've used Amsoil for decades in my 4-wheel vehicles. The advantage of H-D 3-hole is you only need one extra quart in the garage to top off fluids.

[@Dodger2879]

Harley Davidson does not make oil! Harley Davidson does not make plastic bottles for oil either. Harley does however contract a company to make a plastic bottle and add their name and logo to it. It's called, Badge Engineering. Also; spark plugs, leather jackets, crash helmets, boots, ashtrays, ball caps, etc. Get conned if you like, but the standards like Mobil, Pennzoil, Castrol, et al, make great products. (If you preferred HD spark plugs, thank Champion). HD plugs were *identical* - but a few dollars more each and sporting a, "Harley Davidson spark plug number". HD does not buy high end engine oil or synthetic oils like we do either. They buy it in bulk, rebottle it, and sell it as theirs, but at a vast profit stating it is necessary to honor their warranty! Harleys ripoffs are being exposed continually. This oil scam is a good example. This video is spot on, honest and opens up options to consider. However, Newbies can always be swayed by the lies Harley peddle during a sale, due to their lack of experience and the excitement cleverly generated, as HD will finance everything you purchased, "Harley" (but Made In China) that adorns your new "biker" body. Congratulations! You just bought yourself a life! (You really should have demanded your Beacon Score and what percentage they charged you. If a Fiction Fan, you should be imressed at their gall). I worked for two HD dealers and saw the monumental ripoffs occur and the jubilation high fives that followed, immediately following the customer's departure from the parking lot. You could learn a lot from this video; far more in fact, than from a Harley dealer. However, if a "Credit Card Biker" ignore it, as it would likely fall on deaf ears, or sail right over your head. And there are many.

Back in the 70s-80s H-D 20-50 was the controversial oil. Per H-D service engineer that oil was repackaged Cam II. I ran that in my shovel head and it worked well. The 60 wt was misunderstood. The designation went way back to early oil standards and is actually Grade 60. IIRC that made the oil a straight 50 wt as far as viscosity. Where we saw problem was when customers would add STP to their oil. The story was that it made the oil too slick and the roller bearings would slide rather than rolling. This would cause the hardening to wear through and the bearings to fail. Funny thing was that H-D began marketing a Teflon additive about that time. They later put out a service bulletin advising not to use that product.

Back when I rode and played with mainly Shovelheads, Panheads, and on back in time, I swore by HD oil. I still have an old orange 55gal drum (garage trash can) from HD 60wt oil that has the Sun Oil Co (Sunoco) Refinery, Phila, PA address on it. Now, my local Hd Stealerships do not even stock 50 or 60wt anymore. One says they can't even get it, one says they will order it by the case if I prepay but won't say when it will come in. I've gone to Amsoil as a friends auto service business carries/stocks it and I get the friends discount. They also have a 50wt synthetic for my old iron! I've been using Dextron II ATF in the primary for over 30+ yrs. Even since I learned to eliminate the old recirculating engine oil system used from '65~up. If ya look at the components in the primary case, they are very close to the components in many automatic transmissions. And many, more modern all-wd/4wd transfer cases use a 2 or 3 row roller chain and specify ATF! I also feel a cleaner release and smoother engagement of the clutch, regardless of friction plate material. Plus, it's cheaper than anything sold as a primary fluid so I can change it frequently and get that nasty clutch plate friction and metal particles out more often. I did stick with a conventional 75~90wt gear oil in the transmissions. And call me crazy, but I did notice a difference in Slick 50 gear oil. But that stuff is no longer sold. One shop owner I know that builds a lot of manual transmissions for all sorts of racing from dirt tracks to drags uses Z-max in all his builds.

[@djkak5320]

I run H-D lubes in my H-D, Polaris lubes in my Polaris sleds and Ski Doo lubes in my Ski Doo machines. My sense is that the product manufacturer has a high level, granular understanding of the lubrication requirements for each component in an assembly. When a manufacturer is sourcing a lubricant for their product I’d bet that the conversations regarding the properties of the lubricant are high level and very specific as well. A great example of changing lubrication requirements is the H-D Big Twin primary drive. For many years this assembly was sufficiently lubricated by an oil drip; so little, that an open dry clutch would operate in the housing. The 1984 wet clutch required an oil bath, but the dramatic change was the 1.35:1 primary drive ratio which accompanied the 6-speed transmission. The additional load generated by the 1.35 ratio would often destroy the compensating sprocket (crankshaft damper) used on the early 6-speed machines. This version of the comp sprocket was introduced in 1970 and had changed very little since then. A new comp sprocket was introduced in calendar 2009 and this component was advertised to have 700% more capacity to dampen “torsional vibration”. In 2009 I ran an ‘09 FLHX with a Jim’s 131, and the new Screamin’ Eagle comp sprocket. In 2013, after 45,000 miles, I swapped the original engine back in and sold the ‘09. The SE comp sprocket, with 45k, behind the 131, was in beautiful shape and was reinstalled with the original engine. During this time the forums were lit with examples of SE sprocket failures; one person with a Trike claimed multiple failures at just around 3,000 miles. Another good example of “not just any lubricant” is the Screamin’ Eagle 6-speed overdrive transmission. Transmissions with a 1:1 high gear are different than on overdrive trans in that the input and output shafts rotate at the same speed in high gear with a 1:1 transmission, but with an overdrive trans the input rotates slower than the output. Because the needle bearings which support the main drive gear in the overdrive transmission are rotating and generating friction in high gear, unlike in the 1:1 trans, maintaining adequate lubrication of these bearings is critical. Most any heavy, sticky red goo will get to the gear teeth, but what about everything else? What are the properties of a fluid capable of lubricating and cooling a needle bearing, operating under a high load, that is not directly lubricated? The oil lubricating the outer needle bearing of the Main Drive Gear (MDG) must first pass through the the inner needle bearing in order to lubricate the outer. When the outer needle bearing fails, the load generated from the rear drive belt causes a misalignment of the MDG, placing an uneven load on the MDG teeth as well as the teeth of the countershaft drive gear; at this point a catastrophic failure is just a matter of time. In circumstances like these the lubricant must take care of the whole package, whether it’s a transmission, engine, primary drive or what have you.

[@billramsey8934]

For the record, Shell Rotella T4 15W-40 Diesel Engine Oil meets the JASO MA/MA2 lubricating specs of the HD M8 motor.

The drive shaft (Final drive) takes another oil but only needs to be changed every 10k miles and takes 5 minutes to change.

[@frankhabib5748]

Syn3 in crankcase, BelRay in trans and primary. Been running this combination for many years.

[@michaelbooker6881]

Back in 2006 my Twin cam 88 shop manual said that you can use diesel engine oil would do! So I did and sold the bike with 134,000 miles , never had a problem!

[@GixxerFoo]

Nothing wrong at all with using that in the engine alone!

[@zeus9855]

I just happen to use Lucas 20-50 full synthetic on the Dyna and street glide. I use reusable oil filters on both. Most oils that meet the required specs should suffice. If one wants to waste their money buying royal purple or Amsoil so be it. Paying extra for those oils may not preform any better than the lesser priced oils. That’s my opinion.

[@frankmarkovcijr5459]

My 1999 Sportster that has 370,000 miles on her I have used Harley Oil exclusively because I used to get the Chromecast certificates and for a $25 Chromecast certificate I would get 3/4 of oil a quart of training primary fluid and an oil filter and it would be 2658 I would change all three of my fluids for $1.58. I changed the oil twice a year and I changed the filter every other time I must be doing something right because the bike has lasted so long and runs so good.

You would have to ride that bike about almost 39000 Miles a year no way

I wore out the front end from going up and down in '09 and had to get a brand new 09 front end installed on my bike which is why I don't have the single piston caliper front brake I have to Twin piston caliper front disc brake. If you saw my Sportster you would have no doubt in your mind that it covered the miles I said it did my 100/7 BMW my 1977 had 500,000 when I got run over by a car.

That's pretty amazing for a sportster I heard the Evo Sportsters are pretty reliable

[@paulclancy2404]

Dam I feel like my Evo about to blow at 20k lol I'm changing oil every 4 500 miles

[@frankmarkovcijr5459]

@@sll-tt6bj you need to redo your math I've had that bike 20 plus years and I wrote it to work everyday and to job interviews and to temporary assignments when I was in between jobs as well as day trips because I do not drive at night because of all the wild hogs and the textures and the drunks. The bike was a year old when I bought it and it already had 20,000 miles on it. I get 10,000 miles out of a tire and I have put 37 back tires on that bike since I have gotten it. I once called up and add in a magazine that had two rear tires get one front free and they said we don't deal with retail customers I said how many tires do I have to buy they said 10 is that 10 including the free ones or is that 10 paid and then free ones I didn't buy tires for 10 years. Since my Sportster is a low-powered 883 for me to put on so many miles I have to spend more hours in the saddle than somebody who goes like a bat out of hell everywhere. Which is fine for me.

[@jeffwalker1322]

People also seem to not know that Harley recommends the use of 60 wright oil in temps above 80 degrees. I use Motul 8100 X Power which is a 10w 60. Bike sound a lot better on 95 degree days and doesn’t sound bad on 15 degree days. I have also used 15w 60

[@Bostonterrier97]

I like Amsoil full synthetic. Vtwin. My dealership will charge $300 to do a 3 hole oil change. I change the oil myself and instead of every 5K miles, I do it every 3K miles. I like keeping my oil clean.

[@kingkrimson8771]

The oil in an air-cooled engine will start to look "dirty" in a very short time. Just the nature of the beast. After having used oil analysis done I realize I've been wasting money changing oil that often. This assumes of course that your engine is in good mechanical condition.

[@coldairbuick]

Syn3 because it's so darn convenient and the dealers always have it available. There are so many quality oils on the market. Take your pick.

[@scottflora8876]

I run amsoil in my 02 FLHTC after I upgraded to timing gears and S&S 509 gears. On my 2nd season, first season I cut my oil filter apart to look for shavings/metal grit, and good to go!

[@jokenroll7089]

For the engine itself - I agree. For the primary though, over many years I've tried everything possible, from synthetic Lucas ,all the way to mixing a basic gear oil with ATF. IMO, HD Formula+ gives the best "right" clutch feel.

[@victorsamon9672]

Primary oil,,,HI Rev nitro oil,,plus 2once Marvel Mystery oil,,works great,,!! Smooth shifts,,!!

[@dilo777]

Rotella 15-40 while a diesel engine oil actually carries the Jaso-ma/ma2 rating....which is the Japanese automotive standards organization rating for motorcycles.....including wet clutches....so I ran that in my vulcan....it was easy cheaper than motorcycle oil.....never had a problem in 60k miles

[@user-se7vt5ow4e]

And when traveling you can find it at any truck stop.

[@OZARKSHDRIDERS]

I've used different oil's through the past year's...but the last 3 Harleys I've owned I've been using the Harley Screaming eagle oil and I've never been low on oil at the 5k service....its always still full when I check it before I service it, all good points brother💯👊🏽😎

[@davypig571]

I change my fluids too often because I'm a sicko. I even do brake fluid every year regardless of mileage 🤪 I use synthetic even though it's unnecessary since I ride gentle and not in extreme heat.

Schaeffers kit with Harley filter. Been working great. I keep an extra kit in stock at all times plus 2 extra quarts in case and 4 Harley filters since the local Harley dealership has been out of black filters.

[@kingkrimson8771]

I use baby oil sourced from free-range babies

[@leonardstanford1877]

OK here's my take about 8 years ago there was an independent oil test for motorcycles. It listed amsoil number 1 mobil 1 was number 2 syntec came in down the list at number 7 ! I use mobile 1 or amsoil . I have switched customer bikes with 5 speeds to mobil 1 20/50 & the customer wants to know what I did to the trans cause it shifts better. Then it ever has ! On Harley 6 speeds I only use amsoil severe gear 75/140 which has the same viscosity as 20/50 in order to keep from having to rebuild those 6 speeds ! On my personal bike the engine is slightly noiser with mobil 1 then it is with amsoil ! But I do feel like if you use number 1 or number 2 rated oil you are running the best ! So there you have it from 30+ years of working on Harleys !

[@bigblue3568]

The national testing laboratories that test synthetic MC oils have….. 1-Amsoil 2-Mobile 1 HD is halfway down the list $30k for a motorcycle I put Amsoil in mine and notice the Bike runs cooler and quieter.

[@Scott-rr7dy]

Amsoil, is what I run now, and Harley primary oil , which I'm happy with the clutch engagement.

[@fratzog]

I always used Syn3, formula primary and Bel-Ray trans in my ‘new’ bike, 14 fat Bob, because it was recommended from new by the dealer. Didn’t want any friction if there was an engine issue. This year I switched to Amsoil for all 3. No issues but I didn’t have any issues before so it’s all good. My 79 ironhead was bitchy about what I fed it. Noisy with HD 60 or any other 60 except Spectro. She loves that. Primary/trans would give me fits with all the fluids made for that. Hard shifting, noisy, slipping (or grabbing) clutch). Then I tried Spectro 80w for dirt bikes with shared primary and tranny and she loves it. My point: if she doesn’t care what you feed her and there’s no wear and she doesn’t use oil, use what you have. If she’s temperamental like my ironhead, feed her what she likes.

[@NormalishGuy]

I’ve used mobile 1 motorcycle oil “it’s the shit“ smooth shifting in all my bikes including my Sportster shifts like butter.

[@johnkessler9878]

Have used rotella t4 in both my 1996 evo and 2001 yamaha vmax and both still run great after over 20 years. Change every 1500. Cheap. Clean is the best oil.

[@yoso585]

I run quality hash oil when traveling abroad. Never a problem.

[@TracyGunz]

I use Lucas Conventional in my sporty and Lucas Synthetic in my Dyna. I wouldn't use anything else. Just my thing! Use what ya happy with! I see Harley Drag Bikes using Lucas so its gotta be decent or they wouldn't use it!

[@anthonyiannone7618]

75w90 synthetic gear oil in the trans , 10w40 motorcycle engine oil (designed for wet clutchs) in the primary and mobil 1 15w50 oil in the engine. I've also tried ATF Dextron 3 in the primary , but i feel its a little too thin and noisier. I never tried the old ford type f but that did make auto trans clutches bite harder than dextron i remember years ago going to harley dealer to buy engine parts and the counter guy told me he was an A+P aircraft mechanic and i shouldn't use synthetic oil because it made the bearing rollers slide instead of roll , of course i just ignored him thinking thats probably why he was working the parts counter!!! Bottom line is like the video states use what ever you like !!!

[@Since_84]

I've always used full synthetic Castrol Power 1 in all my bikes. Some of the best stuff out there.

[@d1mennis]

I run 20-50 synthetic in 3 holes every 5,000 miles on my 2012 and 2016. Amsoil or Screamin Eagle it don't matter. I run 20-50 conventional oils on my 1986 every 3,000 miles with primary fluid and trans fluid accordingly. The 86 has around 120,000 miles on her, and still runs strong!

[@BerryKreul]

I’ve been using Amsoil for 20 years. When I went in to freshen up my cam chest at 50K miles it showed very little wear. My tensioner shoes could have easily gone another 10K.

I use Mobile1 20-50 for the engine and Primary and Redline Shockproof for transmission , drain and change every other year, never been an issue form my 08 FXDL

[@GavinTurner-w6i]

It depends on your bike, how you ride, and how often you want to change it? I was told to run petroleum fossil based oil when I first had got my bike, then later ran synthetic. I thought the Amsoil, and Royal Purple was pretty good. Full synthetic should allow you to run the motor at a higher rpms, harder without damaging it, but how much it really does I'm not for sure. I do know you don't have to change synthetic as often as the conventional. I changed my oil every 3,000 miles and, say the bikes been sitting for many years, even though you haven't rode it, it needs changed out. Take care of your machines, and they will take care of you.
