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 ...

My dad was a harley mechanic. He was pretty picky about oil but even he would say the best type of oil to put in your bike was....new and clean...

[@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.

The last time I went to a Harley dealer and bought my oil it cost me $58 for three quarts. That's like $17 and something a quart.

[@GixxerFoo]

That's really interesting, I've heard of guys using ATF. I mean the primary is basically the same as automatic transmission with chains and clutches.

Use Amsoil, proper oil for each hole,when I order for an upcoming oil change, I get an extra quart, always have 2 spares on the shelf.

[@davidwilley4524]

I've used several different quality oils and have never had a problem.

[@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

[@PotatoeJoe69]

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.

[@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.

[@Oneminutetofixit]

I found HD oil to be good and slimmey. Thing with oil is the pressure and compression stability. 15 40 diesel oil is one of the best oils for that purpose. It is designed to withstand the rigorous compression and mass pressure that the fuel pumps demand for atomizing the fuel and the cylinder pressure that diesel rely on for running at all. I wouldn't hesitate using that oil in anything I wanted to protect.

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.

[@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.

I am actually not a fan of H-D, just the bikes they USED to make. Harleys are harder on their oil than almost any other bike.

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.

I change my oil and filter every 1500 miles have done for over 35 years in my shovel and I’ll do the same for my twin cam have used different brands over the years never noticed much difference , the cleaner the oil the better in my way of thinking

[@vincentbohn3030]

Done same for same amount of time it works

@@johnswanson3741 you can have all my old oil if you like… and put it in your tractor

[@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.

[@terrywentz4629]

I’m using Spectro 25-60 (not a typo) Dino oil in the engine at the moment (‘05 Road King). The top end seems to be a bit quieter. Prior to that I have been using Amsoil synthetic for years.

[@frankhabib5748]

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

[@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 !

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

[@GixxerFoo]

It's even in the owners manual that you can run it as an alternative. But Harley manual language puts it that running diesel oil is a last resort and get your bike to the dealer service department as soon as possible to get a fresh Screamin Eagle Syn 3 oil change lol.

[@riseabove5105]

Been using shell rotella on all my bikes ..put over 100k on dynas always ran great

[@grgygantz6760]

In my sportster I use BellRay, same as what we used in the bikes that raced motocross. In the road king. I use Red Line.

[@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.

[@joehuro2906]

I use Lucas synthetic it always on the shelf at all my local auto parts dealer. I ride alot and will change my oil at least 3times during spring and summer. Budget wise I go Lucas or Castrol conventional oil but change at 3000 miles. Lucas synthetic gear oil is always available also.

[@yoso585]

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

[@aaronmilliken5213]

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.

[@carltozerjr6736]

My local Harley dealers have been selling Amsoil at their dealerships for some time now. It made a world if difference in my 08 Fatboy. Shifting is smoother and she euns cooler. Using it in my newly aquired 13 Road King CVO now.

[@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.

[@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.

[@danonoveh8114]

I didn't see Schaeffer's on your list , I have been running that in my 07 96ci it seems to be doing great👋😁

I use 20w50 mineral oil in my Twin cam 88 engine - I change it every 2500 miles (4000 km) or once a year. Gearbox 75w140-Change every 5000 miles (8000 km) or once a year. Primary oil 10w40 synthetic motorcycle oil- Change every 5000 miles (8000 km) or once a year.

[@Baloski46]

I'm with you on Amsoil!

[@paullesho2693]

I found Amsoil is the best. For the lubrication and much cooler running. I take a spare quart on long trips, but they do not use any.

[@GixxerFoo]

That's what I've found over the years, I kept going back to Amsoil.

[@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.

[@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!

[@martinwall7297]

My 02 RK was brought new then, I still have it and ride it 97,000mil. Always used mobile 1 syn extended oil 15-50. they stoped making extended 15-50 it had more zink,moly detergents, and compounds than reg mobile 1. so I use 15-50 reg syn with a bottle of stp to make up the difference. in cold weather I don't use stp it raises the viscosity to about 25-60. but in hot weather it works well. changed my chain drive cams at 45,000mil to fuling gear drive package, the old chain cam shoes had about 75% wear. I attribute that to mobile and stp. in wally world both oil and stp cost me $26 I have a reuseable filter so no cost there. mobile 1 20-50 mc oil is $10 a qt.that's $40 just for oil,I just can't see the extra $$$ because it says motorcycle oil. I've used rotella T6 15-40 syn diesel and stp to bring up the viscoty, works as good if not better. and is cheaper $$$ per oil change.

I change it at 3,000-4,000mils. never a issue with any bike. chain tentioners were swapped out at 45,000 for fueling cams and S&S gear drive on my RK, and the shoes still had meat on them. good quality oil syn if possible is the key.

I agree motorcycle specific oil, the proper weight. I personally use Castrol 20w-50 full synthetic V-twin. I get it from Amazon less than 10 bucks a quart. It has been good for me. I don't like paying 20 dollars a quart for snake oil.

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.

[@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 !!!
