Engine Oil that has never let me down.

I've used this for as long as I can remember, never had heat problems, never lost a motor to wear, never had it come out any different than it went in, very durable oil IMO.

Long as it's around here's a link that should help anyone unfamiliar with motors in general and first time motorcycle owners.

That's what I've used too in both bikes for the past 7 years. Never had any problem either, and wear residuals are very low as verified by used oil testing. I get it at Canadian Tire or WalMart.

I use the 20w-50. Great stuff.

I have used the 20-50 regular grade in everything from lawnmowers to bikes to cars and trucks anything that uses motor oil. I buy it by the case and have done it for years with no oil related or clutch related problems ever. I have used the 4 stroke bike oil before but I normally run the regular oil because keep it stocked up for everything else.

That is a good oil. It is the same formula as their raring oil. A bit expensive for my taste, but you are paying for the name and for a specialty oil.

When I bought my KZ-750 in 1979, the only oil the dealer used was castrol GTX (car oil). I used it for decades. I have 82k miles and still original bottom end. castrol is pretty good stuff.
