Castrol Power1 4T 10W-40 Full Synthetic Motorcycle Oil, 1 Quart, Pack of 6

my mechanic said this oil dissipates heat very well and you can run your idle your bike in summer for one hour or more and the fan will never come on. i used to use diesel oils in my motorcycles, but i learned that that oil has possibly anti wear additives in a higher concentration and that is not a good thing in gasoline engines. However, everyone who reviewed this oil thinks it is actually a man made synthetic. Nothing could be farther from the truth. There is not one drop of actual synthetic base in this crude oil product, but it is HIGHLY refined. Anyone wishing to use actual synthetic base oil must buy 100% Synthetic.

It makes the engine run smoother, the gears shift more crisply, and the throttle response is more sensitive than other oils I have tried.

I have used Castrol in my motorcycles, cars and trucks for many years, and it is by far the best oil. Valvoline is the only other oil that comes close to them. I have used it in an SRT4 Dodge Neon, a WRX Subaru, and a CLA-45 AMG Mercedes. None of them ever used a drop of oil, even after 90,000 miles. I have owned over 100 motorcycles (I'm 72) and the same result, not a drop of oil. V Twins, vertical twins, three cylinder and four cylinder bikes - Dirt bikes, street bikes, even bikes I raced. Didn't matter, they all never used a drop of oil. I even use it in my old C Class RV with a Chevy Duro-max motor, and not a drop. FYI, I only use 100% synthetic oil, and I always buy the best oil filters designed for Synthetic oil. I also change it every 5K miles.

As listed

Oil works great used for last 39000 miles on my z900.
