Best Oil For Harley Davidson

[@oregonoutback7779]

With over 50 years of riding under my belt, I have run engines with and without oil. I have to agree with John, with oil is better :)

[@tax905972]

@John Maxwell-everybody likes different oils but what test have they done on Harley engines or transmissions? Harley tests their oils on Harley components. I'm pretty sure they got together with their oil supplier to find the best additives for their bikes, especially if they're putting a warranty on their products.

[@gnarlytothemax]

Managed to ride my Sportster maybe 5 miles at fwy speed without oil. Got oil back in it, and it's been running fine ever since. Maybe the fact that I use mobil 1 synthetic helped a bit, I figure most motors would have seized by tthat point.. @@CSIS-Spy

[@richk.4020]

Hey John, me and my Dad we just run full synthetic, in all three... he's got 77,000 on his bike.. I got about 37,000 on my bike.. I got a 05 Wide Glide and my dad's got an 05 Fatboy... never had any problems except for the cam chain tensioners we had them replaced.. but that wasn't due to the oil.. I do my own service.. thanks for your cool videos!

[@matthewclagett857]

Hey John. Love your videos. I have heard the arguments against putting Amsoil in all 3 holes before. What gave me the confidence to put it in the gear box is that Amsoil posts all their oil test sheets right on their website. I took some time and looked at their shock tests, breakdown tests, and other tests between their synthetic engine oil and their gear and tranny oils. The results of the tests showed that the engine oil performed at or better than the gear specific oil. That's why I imagine that they can guarantee their oil safe for all three holes. Understanding that they have no liability in making that claim, I can appreciate the scientific method they used to come to that conclusion. As always, YMMV. Also, you spoke about convenience. With the SE110 motor, it takes exactly 6qts if you add up all three holes. If you get 3 different oils, you wind up with a little left over in one jug and needing to buy a whole other quart to cover a couple of extra ounces needed for one of the gear boxes. Using the same oil for all three holes makes it very convenient when ordering my oil change kits. Harley would DEFINITELY convert me if they made the gear oils in quantities that actually matched the capacities of the cases they were being poured into.

Scams oil

[@kevinyoung1447]

That’s exactly what I run, Syn 3 20w-50 in the engine and HD Gear Oil 80-140 in the primary and transmission! Thank you for your content John, keep up the good work!

[@jmeyer58]

Great video and nice job explaining that "what ever makes you sleep at night" is what you should run. As a retired automotive instructor I have given the oil brand speech to hundreds of high school students and I agree with everything you discussed. I have been running Syn3 in all 3 holes since my first touring bike in 2003. NEVER had an oil related issue but I think I will switch to the new gear oil from the motor company next trans change. Yes, everyone will have a reason to run their favorite oil but you are correct, it is more important to have oil in the bike, the brand is secondary. One addition is that the oil should "meet or exceed manufactures specifications". To many people run an oil that does not meet the specifications and then feel there was something wrong with the oil when it was not rated to do the job asked of it. Keep up the good work John!

[@mikebrabant4170]

Been running Lucas Oil for the last few years in my Ultra Classic and it does the job and runs a little cooler and is Synthetic. Trans shifts a bit easier also.

[@BrewCityRider]

Yep, lots of good options out there, lots of opinions, and lots of experts. For my twin-cam I use Mobil1 V-Twin full synthetic in all three holes. It is highly rated by both studies and users, it is readily available across the country, it is formulated for use in all 3 holes, and it is inexpensive - I pay 9 bucks and change per quart. Works for me.

I'm a 69 yr old on an 06 1200 Sporty. I use Mobil 1 20/50 syn in engine and trying Spectro in trans, that was recommended by a local bike shop, since I installed a 9 disk Barnett clutch. Shifts pretty smooth.

[@OcotilloTom]

I agree about the Syn3. I switched to it from the Harley 20/50 on my Sportster 48. Within 50 miles I was having valve chatter (I never had) when running thru the gears. Went back to the local Harley dealer...same one where the parts guy told me to switch. The mechanic I saw so NO, don't put Syn. in a Sportster, stick with dino. oil. So now I'm running straight HD 50 wt.. Bought the Bike new in 2014, now it is 5 years old with 10,000 on it. Never have had a problem with it. I live and ride in Arizona where its in the 110-115 (f) degree range now. This is my 3rd. Sportster since 1964...I keep them a LONG time.

[@ThatBobGuy850]

That's funny, Tom- My dealer said, "Absolutely not!" to synthetic oil in my '86 (first year Evo) Sportster. "It's too slippery," he said which, I gotta tell ya, got my red flags a-raisin'. Oil...can be too...slippery? Anyway, I switched to full synthetic and the bike LOVED it. I live in Florida where it gets not, but not Arizona-hot ;)

[@sswcustomsewing4276]

I love the Sportster because they run forever, easy to maintain, plenty fast, reliable, and they will down dirt bike trails if necessary. I wont part with my Sportster it is my favorite of my bikes always will be.

[@kidrock7462]

I run AMSOIL and made my bike shift a lot smoother plus it eliminated the surge to move in gear, made it a lot quieter, I was so impressed by this oil I became a dealer. If you really wanna see the difference go watch the videos comparing different oils. The AMSOIL came out on top on each test against all oils. Plus I found out that the Harley oil is made by Sunoco, not a very reputable oil in my opinion.

[@RK-de5wg]

Then why isn’t it ever supported by and sold by Parts Unlimited, Tucker Rocky, Western PowerSports etc? Why is the only real profit going to the guy who sells it, like you, not the dealer at .50 CEnts profit per bottle? It makes Zero sense to sell that oil at your store.

[@justrobb6526]

John - you did an excellent job touting the best oil (for you) is whatever is the most convenient. As for me, I don’t spend $32K+ for my Harley only to skimp on a synthetic BLEND fluid because it says H-D on the bottle. Amsoil all the way for my baby!!

just curious what do you run in your transmission synthetic oil, or gear oil? currently I'm just running Harley synthetic oil the same for all 3 holes n change the oil 3 times or more a year to keep it clean as possible, but now rethinking n running gear oil in the transmission after watching this , it just makes sense to me, but keeping it simple n clean and consitent has worked best for me over the years.

For me it's Lucas 20-50 full synthetic in the crankcase, Lucas full synthetic 75-140 in the trans, and Lucas primary chain oil in the obvious reservoir. Good tip, pick an oil and stick with it, probably not a good idea to switch between brands all of the time.

Did a 3 hole service on my buddies 02 NightTrain while I put Apes on it and replaced his chain tensioners... Used RedLine's complete kit....

[@PotatoeJoe69]

Well, here's what I can share on the topic from my personal experience: running Redline Racing's 20w50 V twin oil has ALWAYS made my bikes run 10-12 degrees cooler, as per temp gun on the heads. It has also ALWAYS quieted some of the mechanical noises down. So, I'm not saying it's the best oil ever, but it's pretty clear too me that it's working some kinda magic. It's expensive as hell, but for less heat and less noise (therefore one would assume better lubrication and less friction)? I'll spend the extra $$$

Ever since I bought my Harley all I use is Harley synthetic. Right after the first thousand miles I changed all of the fluids to Harley synthetics. That's all I have ever used. I take excellent care of my bike. Even my local dealership where I buy my parts have told me that I did not need to change my oil as much as I was. They told me since my bike was still under warranty I did not have nothing to fear by waiting longer to change my oil. I explained to them I wasn't going to sit around all summer waiting for the dealership to replace my engine. On one occasion I had changed my oil on a Saturday and the following Saturday I had taken my bike for a long ride. Coming back there was a huge accident and on this stretch of road you have to stay on it until you get across the bridge. It was a hot August day and my engine was so hot that it was burning me through my jeans. The oil temperature was 300°. I had to put the bike on the shoulder and get off of it. Finally the road opened up and once I was back up the speed everything went back to normal. As soon as I was back on the other side of the bridge I went straight to Harley. Everyone there knows me I have been using the same dealership for years. So I went inside bought everything to do another oil change and that's when the parts guy asked me what happened to the stuff you got last week. I told him what had happened and he went on to tell me that I didn't need to change the oil again that it was synthetic and it's made for that heating cycle. He did not persuade me enough not to change my mind so I got everything I needed. When I drain all of the fluids they all still look brand new. Even though the fluids looked clean I still had no problem with my decision to change it again. Every year when we come back from Daytona from bike week I change all my fluids before riding season back home. Enjoyed your video look forward to watching more of them.

Ahhhh, glad to hear someone make sense. I sell oil in a bike shop and mostly this is what I also say. As long as you can find an oil that's from a reputable brand or seller, and the oil is made for your purpose, and you're running the correct amount of clean oil, go for it. Stressing out over BelRay vs Motorex vs Castrol vs Amsoil etc is gonna give you a heartburn. Don't, however, put long life car oils in there esp. if you have a wet clutch. That's going to be possibly really expensive. All that said: Of course more expensive synthetic oils *are* better. Conspiracy theories in a *very* contested market are just silly. We can look at dozens of videos and reports showing you that they *do* last better. Don't believe the myths that "synthetics make your bike leak" or "synthetic makes your clutch slip" and whatever. What remains for you as a buyer and user to decide is how much is that better oil worth to you and what can you afford.

Shifts easier and cut down on the chatter and goes into neutral allot easier now ! Thought I may need to adjust the chain but with only 10'000 miles on it , it was right where it was supposed to be ! My Dad always said change that oil before its due and that engine will last longer then You ! He worked for Shell Oil many years ago . I think He was a Backyard Pitchman ! LOL

[@DanDickgrafe]

I’ve been very pleased with Shaffer’s fluids, but I like the fact that the Motor Company offers a very good gear oil as an option for those who don’t run synthetic. Like he says, the most important part is that there’s actually oil in the bike.

[@mikeskidmore6754]

The Bottle of HD Branded Oil that John Held up is Synthetic. I had to play the video at 25% speed in order to pause it on the frame 80W-140 Synthetic ..

[@rclarkrep100]

AMSOIL VTWIN for me because I took the harley out of my motor with better pistons, cams etc. Recomended staying on top on oil changes. HD oil is fine as well. My first Harley but my last. Great Video!

[@cram9300]

Thanks John, really great info! I ride a 2010 FLHTK and I normally take it to the dealership for service. I am looking to do my own service in the future, and appreciate the insight.

[@FlyKaleb]

2000 Road King. Loves HD360 20w50 and Formula+ in trans and primary. Easy, tried and true. Nailed it John, having oil in the bike is half the battle.

[@bartphillips6391]

Mobil v twin 20-50 synthetic in the engine and BelRay in the trans and primary. Been great so far!

[@raymondmacwhinnie5562]

So here is a data point. I have a 2017 MW8 Road Glide Ultra 42K miles. NH owner so limited winter riding. I have been running Syn3 in all three holes since the first oil change. Motor is running great, bike shifts just right, and clutch feel is still awesome.

[@rockyrauf2529]

I bought my first Evo in 85. Running a straight was definitely a no-no. That being said I live in Canada. I used ask service techs about running synthetic. I was told no, to slippery. After a while I went and had my top end cleaned up. Then I started using Amsoil. I will never go back to fossil. Harley doesn't make any oil. They tender it out to the lowest bidder, so essentially the cheapest synthetic you can find is your SYN3. I have had people and read that SYN3 was the junkiest oil. Too thin and a lot of noise. They went to another brand of synthetic. I found it underhanded that Harley would say don't use synthetic till they started marketing their own crap brand.

[@hubster4477]

Hahaha finally a truthsayer!! Same with Honda oil or Yamaha oil.

[@AudriusN]

"I was told no, to slippery." - bullcrap, tell them to educate themselves. " Then I started using Amsoil." - 20W-50 Synthetic V-Twin is PAO based, real synthetic. "They tender it out to the lowest bidder" - same with Honda GN, Yamalube and others. And they have different suppliers in different markets. Nothing special, everybody does that.

[@Johnr37us]

I’ve always done my on service. I’ve just used the owners manual. As for oil brands I used Amsoil. I got a new CVO Limited on yesterday ( previously had 2018 Ultra Limited) I also use the Amsoil gear oil. But I agree with you I have even used the oil filter trick.

Hey John! Great video as always. And great advice too! Thank you for not just parroting the H-D line about using their oil and *only* their oil. Using whatever oil let's you sleep at night is probably the best advice I've ever heard.

2012 Fat Bob Stage II Barnett Scorpion Clutch I live in Phoenix and have run Mobil 1 in all holes for 3 years without issue. I ran Amz Oil & Redline before that. Barnett actually recommended Mobil 1 (as well as a couple others) when running that clutch.

[@pokechopracing8862]

Great content as always John, I have a 99 FLHT that I run redline in all holes and change at 2500 being in the high desert of California and road temps over 130 at times it tends to break down quicker.

[@lisar3006]

Always had Pans and Shovels and didn't know much about synthetic oil or changing oil in three different places until I got a twin cam. This was helpful and straight foreword.

[@Peter-976]

So John, now that we know HD`s syn gear oil is 80w-140, I`m guessing their formula+ is 80w-140 also? As for the synthetic motor oil, the correct amount, weight and changing at the recommended intervals is more important than what brand you use

[@beardwrench]

Formula + is approximately 90 weight

[@ojalaquesi1]

what about is castrol 80w90? is good???

[@richardcarlisle6169]

My Harley is a 2015 Softail Slim with the 103B twin cam engine. Now, with 30,000 miles, I have discovered that "BelRay 80W transmission oil" works best in the chain case. BelRay says it is "Created for all motorcycle transmissions equipped with wet clutches". I get the best smooth and complete clutch engagement and disengagement of any oil I have used, especially in cold whether when you have to rock the bike for and aft to break loose the clutch plates. I believe the product is of the GL3 speck. I am using MasterPro full synthetic 75W140, speck GL5, in the gear case. I get easy shifting and minimal "Clunk" between each gear. The engine oil tank takes 3 quarts of Harley "Syn3, 20W50" and I use the "K&N" brand oil filters. The GL5 gear oil and the K&N oil filters are in O'Reilly Auto Store locations in my area. The BelRay 80W comes from a scooter shop and the Syn3 comes from the Harley dealer.

S&S specifically says or used to say run Mobil 1 V twin in their engines so if they say it is a great oil I would take their word for it over anything that Harley Davidson recommends. I have ran a lot of Mobil 1 V twin it is a great choice.

Ok not only informative but entertaining as well, thanx, Now in my early bikes I run an aircraft quality oil, summer or hot weather. 70 at single viscosity, winter( not to severe) 50wt single) Later models I run a 20/50 full synthetic, there in no close dealer closest is over fifty miles therefore I run Mobile 1 v-twin with K&N filter, love that nut on the end for removal and of course reinstallation. You asked for it, that’s how it’s done in the country, have a great day and again, thank you for your efforts Whop

My FXDLS plows through SYN3. Switched over to Amsoil and haven't looked back.

[@mikeheckman4995]

100% synthetic is the only way to go. Designed for a purpose, rather than being dug out of the ground. Even the lawn mower gets it.

[@mysticmadman5961]

@Mike Greer - It burns it up and requires more oil to be added between changes

[@larrybraden6640]

I changed to Amsoil too. Better oil pressure and way less noisy.

[@rodzimmerman1979]

I have run Red-line V-Twin and Amsoil V-Twin in all thee holes with four different Harley's over two hundred twenty thousand miles with no problems. Always used OE oil filters. I have never had to replace a clutch or primary chain doing that either. I am going to be using Amsoil 75-140 extreme gear in the trans of my bikes now because I closed my auto repair shop and retired and have some left over so the price is right. I would not have any issue running Harley oil or Mobil 1 as well. My Harley dealer is 15 miles away and Amsoil can be drop shipped at my doorstep. There is a very good independent shop near me that uses and recommends Mobil 1 so there you go!

[@aldonova1112]

HD dino engine,formula+ primary, redline trans. Works for me

[@fonziesgarage7187]

I just changed my “three holes” I’m thinking the trans can go at least 4 times longer than the engine oil and probably the primary oil too. Waste of money to do all three holes every engine oil change. Glad they started making 20w50 in full synthetic, that stuff is far superior especially at hot hot temps!

Amsoil V Twin 20w-50 in engine n primary & Amsoil Severe Gear 75W-90 in transmission. I didn't like how it shifted with 20w-50.

Steven Wallace I do the exact same! I tried HD Syn and was getting a lot of engine noise and shifting noise. Did some research and changed to Amsoil; viola, no more noise! Recommend Amsoil hands down. Anyone disagrees, do the research.

[@mumbler5644]

Love your videos . I do my own oil changes and pay the dealership a hour once a year just to give it a good look over and I maintain extended service , which always pays for itself . Thank You for your Videos and the advantage to buying the synthetic oil from your harley dealer also shows proof of maintenance if something were to go wrong . Now I will say I had some engine parts powder coated over the winter. I was so impressed the top of engine (under the rocker covers) was spotless looked NEW at 31,000 miles. Thanks again John

[@jdkmboy]

HD syn3 all three holes. Cheers Bro and safe travels this weekend.

[@mikeb46]

I can attest to the protection provided by Amsoil. But make certain it is the variety made for air cooled engines. It can handle the higher heat better. My 2000 wide glide now has 85,000 miles and a recent check of the cam tensioners showed they are only half worn down. I plan to replace them just to be safe but that tells me the Amsoil is doing an amazing job of lubricating the chain and the tensioners.
