Been using Mobil products since before synthetics. I did have a Suzuki Hayabusa that went 70,000 miles without needing valve shims (checked every ~12K and it was within Spec). It ran Mobil 1 MX4RT racing 10w40 the whole time. My ZX-14R has 30K on it.. same thing.. the cool thing? it's not that expensive.. cheaper than Motul, Royal Purple, Amsoil, etc.. I own a motorcycle for about 70K miles, then sell it. Other tried to tell me to use Shell Rotella T6 5w40 (diesel oil). I'm happy with what works.. Just change your oil before it goes black, or when you can feel the transmission feels notchy..use the recommended viscosity... and don't forget the filter... you'll be fine

[@richardkrammes2222]

I have been reading Cycle World since 1962 ( first issue Triumph Bonneville, third issue Norton Atlas). It is good to hear you young fellas, ( Hoyer and Cameron ) talking oil and life. I promise to keep riding, if you two promise to keep doing these discussions. Mr. Parkhurst is proud of you two.

[@frankdepalma4409]

I bought new a 79 xs1100 special that has been my only road bike,and still running great. I used automobile oil for the first 15,000 miles according to the manual, now use motorcycle oil which quieted it down and even shifts better. The old ride benefiting from New oil technology. Things are going great for the retro bike.

One thing I wish you had covered is that an oil like Castrol GTX 20-50 that Iranian my Norton Commando is not the same formula because of catalytic converters. I just found Castrol GTX 20-50 Classic which has the high levels of ZDDP needed for my flat tappit Commando. Do not use with cats.

Listening to Kevin talking about Oil is much more informative than reading a book.👍

[@mikeskidmore6754]

In a Motorcycle it costs less to change the Oil than the Oil sample costs.. My Local Power Sports dealer raised the price for a Fram Filter for my Buell or a Kawasaki Mule from $8.00 to $12.00 I searched the Part # and Walmart sells the same part# Fram filter for $4.11 I used to buy Aftermarket Filters for my Yamaha for $4.50 the same filter fits my snowmobile that uses a Genesis Motor based on the R-1

[@johnhartley3022]

For my first 20+ years of riding i put castro gtx in everything, bikes included. Still have my wes cooley zuke with no issues. Went to motorcycle oil in the last couple of decades to improve shifting due to better shear characteristics but couldn’t say I noticed any difference

[@MCTeck]

I had a 1976 Yamaha DT 400cc2 stroke. When the engine was cold, unless I pulled the clutch in,out , the clutch plates would stick when put in gear engine would stall. Started using mobile 1 synthetic motor oil in gearbox. Never stalled cold again! And much better shifting!

[@johnschlesinger2009]

Very informative and enjoyable. What wasn't talked about was what happens when a motor is run for short journeys in cold weather: condensation forms, which is acidic, and the motor doesn't get hot enough to evaporate the condensation, which results in contamination of the oil. In cold weather, a motor needs to run for about ten miles after it has reached optimum operating temperature to allow the condensation to evaporate. This is why buying a car with very low mileage from a little old lady is probably not a wise thing to do!

[@keithkeller6509]

Great episode. Enlightening and entertaining. Thank you.

[@exothermal.sprocket]

If you're bored one late evening, get on a motorcycle forum and tell them that Rotella Diesel oil is inferior stuff, even if it passes wet clutch requirements, and people would be better off using a motorcycle specific full synthetic racing oil. I'm sure you'll be entertained for weeks in that thread.

[@craigg4246]

Mobil 1 used to be a PAO, or PolyAlphaOlefin, but today is a group 3 hydrocracked mineral oil. If you want a PAO, you need Motul, Amsoil or Kawasaki synthetic. I use the Amsoil in my 1050 Vstrom. With 25,000 miles on it, I have no clutch basket chudder they are famous for, shifts great up and down, and uses no oil at all. After 3000 miles, is still right on the full line.

[@nickrider5220]

Love these detailed talks 👍🏻

[@bruceparr1678]

I raced a TZ350 A and C at Bathurst over a few years. Manual recommended R30 at 15 to 20 to one. This mix carboned up the cylinder. Castrol and Bel Ray brought out low ash oils which were great until it got cold and wet. The carb slides would freeze full open. We soon went back to R30 when the weather got cold.

[@markpavletich747]

Brass slides would have been a better fix.

[@donniebaker5984]

About synthetic oil.. I was working for a contractor at the Marathon oil refinery as an electrician.. I was running conduit in the product line pipe racks... What the difference was between regular oil and synthetic as it was told to me by a Marathon oil refinery engineer who should know.... What it boils down to pardon the pond,, synthetic oil molecules are all exactly the same size.... Petroleum oil is all different sized molecules from big to little and guess which ones break down first ..

[@donniebaker5984]

I use mobile one V-Twin oil in my XR 1200 Harley Davidson. I use this in the engine only that is 20 w 50 model 1 v-twin oil.. the transmission and the primary are connected together and share the same oil as there's no separation between the two.. Harley-Davidson says to use 80 weight gear oil ... This stuff makes your clutch plates stick together, so the clutch plates are still stuck together and engaged when you put it in first gear.. this is what causes that horrible clunking sound when you first put your new Harley in gear.. this noise is caused by the dog engaging on the gear sides without disengaging the clutch plates that will eventually destroy the transmission of your new Harley.. on a Sportster you do not have much choice because the transmission share with the primary.... So I use 10 w 40 engine oil formulated for a Japanese motorcycle with the clutch transmission and engine all one oil that is made for clutch plates to disengage.., I have nowhere no noise and my clutch works perfectly.... As long as you have an MA endorsement on the back of the bottle you're fine... Or a big twin Harley use what they say to use in the transmission...but for the primary that is separate oil use automatic transmission oil that won't cause the clutch plates to stick together ... And enjoy your Harley for the very first time with no noise, nowhere and tear on the transmission at all.... In your primary all your lubricating is your primary chain and clutch bearing . And this is what automatic transmission fluid is designed to do... And the plates in your clutch will work perfectly just like they do in an automatic transmission

Mineral oil < Semi Synthetic < Synthetic A full synthetic always gives you better results than a mineral or semi-synthetic oil. The semi-synthetic is a good compromise if you can't afford a full synthetic. 🙂

This is a good vid and very informative if one is a PHD. I change my MC oil and filter at 3000 miles . I have a Honda Rebel 500 and a Grom. I use Honda synthetic in both.

I have reached the point in my life where these two bikes will be my last ones and I expect them to last till I die. So yeah it's important.

[@howlinhog]

I've been a professional repair tech for over 45 years. One of my first run ins with a customer who thought he knew more than the manufacturer was this guy that had decided he was going to get rid of "all that emissions crap". It's the early eighties and manufacturers were really struggling to meet emissions standards and this can be seen with a mess of vacuum hoses, controls, air pumps and the advent of electronic spark control relying on info from a knock sensor. This guy disconnected and threw away every single vacuum hose he could find (including the choke pull off). He disconnected the ESC connector from the distributor and unplugged the knock sensor (it'll still run). The cherry on top was turning the air cleaner lid upside down. By the way, I'm in Michigan, you don't get to remove your choke pull off and you don't get to remove the heat riser that keeps your carb from freezing over. Not sure how I didn't get fired but I went off on this guy for claiming that his brand new truck was a piece of crap and warranty better be taking care of it. I told him in front of his wife and my service manager that he was without a doubt the dumbest guy I had ever dealt with. I know this isn't a response about oil, it's a response in regard to how many people think they know better than a team of very bright people that actually can build a machine that will perform amazingly well in spite of stupid people. In regard to motorcycle owners (and I've ridden my whole life) removing your exhaust system that has been engineered to get the best performance and putting on a system that is chosen specifically for the way it sounds may be the dumbest thing I've witnessed.

It was explained to me by the wise oldtimers that many of the older style engines design were made to utilize the accumulated vanishing to help mainting the engine to run smoothly much like a automatic transmission that if you change the automatic fluid to often you rinse the clutch packs to the point that friction material that it no longer functions

One of the best Harley mechanics I knew also used to build short-track small-block V8s for several racers. He swore by the old 240/360 HD 50wt. He showed me several motors torn down, bearings, cranks, pistons, cylinder bore run with HD 50wt and those run with ''racing'' oil. It was obvious the HD oil was far superior. This was before synthetics became widespread. I knew some motorcycle drag-racers that ran big-bore GS and KZ/GPz motors and used Pennzoil for air-cooled aircraft engines.

[@dereksmith5019]

Well , thanks for this , wasn't quite what i was hoping for , but i heard , the right oil for your Velocette is 20/50 . That's good enough for me and my '65 AJS 16 . The hard part is my supplier can no longer get any Castro oil in any weight .

[@gothicpagan.666]

In the UK we had a company called Chatsworth, their first pressing 40 grade oil saved a lot of money and costs for anyone who knew about it. If you had an ordinary wet sump oil pump the oil pressure release valve needed extra flow or very carefull warm up.

Steen C synthetic. Ran this in a YM1 305 Yamaha Cataliina in the early 70's. The model with iron barrels. Yes there was a Yamaha 305 that came with aluminum barrels too. One year i put near 30000 miles on that bike. Pulled the heads and you could see clean aluminum on the tops of the pistons with just a slight dark swirl on them leading to the exhaust port. Steen ran clean. I ran it through the Yama-Lube system. Didn't much like pre-mix on a street bike. I had raised and widened the exhaust ports and smoothed the transfers. Heads were milled a little. Carbs were bored a MM or two as were the mounting spigots on the barrels. Had J&R chambers on it. Man I miss two stroke twins.

[@terrydepew1252]

I should add prior to using Steen C all the the other 2 stroke oils left carbon on the tops of the pistons. Some worse than others.

[@eddiebaird8368]

Awesome topic, I use Honda GN4 oil and I'm happy with it. However when I first started riding in the 80s I used regular Castrol oil and that worked good too

I think another video on bearing types in engines would be interesting. Such as why dirtbikes/singles use roller bearings and none seem to use journal bearings? Journal bearing sensitivity to momentary oil pressure loss could be a factor with normal oil pump offroad, but couldn't you use journal bearings with drysump system? Many dirtbike engine failures I read about online seem to be from roller bearing failures, they don't seem to last super long like journal bearings. I know it's cheaper to use roller bearings, and you don't see car engines using them...

These videos are priceless! I'd love to hear opinions about reuseable filters and using the same oil for the engine, primary and transmission on some Harleys. I use specific Redline oils.
