Engine Oil

[MedicineMan]

I have been told (by other riders, mechanics, and owners manual) that the use of "Energy Conserving" oil is DEATH to the clutch in my 750 street bike.
Only oil without additives.

The difference is the "wet" clutch and it slips til it burns out.



What difference does this make in the ATC's???
Specifically the "automatic" clutches.

Should we also avoid this in these trikes???

I know Castrol 10w40 does NOT have the "evil" additives.

True It affects them the same, Some here have said they have ran that oil and not had problems But when your buying oil why not just get the right suff.

zinc is one of the main things that energy conserving oil does not have in it and i have seen it eat cams in flat tappet V8 motors.

valvoline racing (vr1) as well as many other racing oils still have all the good stuff.

Actually it's a "slicker" additive that causes the clutches to slip.

Synthetics with graphite polymers will do the same.

But my question was, since I don't see it addressed in the manuals (maybe mans too old), is whether it can/should be used in our machines or not.

I don't intend to even try it in the 200es or 70 at all, but it would be nice to know for sure.

The little circle on the back of the bottle/jug will actually have the words "Energy Conserving" on the stuff I'm talking about.

+1 on the Valvoline.
I use it exclusively in my 750 Aero.

i hear you but its the metal on metal rub that this new oil dont protect against that has me not useing it.....so i dont know about the clutch.

the zink was messing with cats and sencors on new cars and since most new cars have rollerized motors they took out the zink and im sure they added some other things but its the lack of zink that kills old motors

I'm sure this will spark a debate...it always does...but, here goes...


DON'T USE AUTOMOTIVE OIL IN MOTORCYCLES.


Auto oils are motor oils ONLY.

Motorcycle oils are Motor,clutch, and tranny oils.

auto oils will not stand up to the abuse that mc/atv oils place on them.

yes it will still lubricate them and no your motor won't blow up if you do use it.

HOWEVER, a mc/atv engine run on pure mc/atv oil will last longer and run better and stay cleaner.

IE, take two identical mc/atv motors, run one 10 years on nothing but auto oil and the other on nothing but mc/atv oil. after those 10 years the one run on auto oil will be worn out, the parts will be going out of spec and you'll see sludge all over the inside. the other motor run on mc/atv oil will still be within specs, and the inside will be nice and clean.


enjoy the fireworks :cool:

I tend to go more with Black Sheep on this. I for one have tried the motor (auto) oil in bikes. The clutches take the worst part. Lets just say, the clutches will last at LEAST 1/3 LESS in regular motor oil than with M/C oil.
I have seen in newer dirtbike engines. The ones with 2 oil cavities. Engine sealed from transmission. People have been using automotive (actually Mobil 1) in the crankcase side. and motorcycle oil in transmission side. They last as long if not longer than the ones that use motorcycle oil in both. The ones with car oil, just seem to turn faster. Just by going on sound.
I can see where separating the trans from crankcase oil would help a lot. It keeps clutch fibers from getting into the oil pump and in bearings on rod and crank.

thats why i use vr1, it's rated for gear shear
