Does the conventional oil Valvoline VR-1 fall into the category of a race oil? Currently, using 40w and change every 20 hours. Thanks.

I don't think your lifter failure was due to oil, either a bad lifter or weak valve spring causing it to bound on the cam,

You need to change your avatar, The bright colors make me dizzy.

Please don't change the avatar ... but you could remove the bright colours.

lol... Yes but if the colors were removed the dizzyness would stop, but the horniness would begin... lol J

What are the test results on this brand :

That is what I've been using upon recommendation from the guy who built my engines. I change the oil every 25 hours.

Thanks in advance,

Some of us are able to be dizzy and horny at the same time.

Not an exact application but my brother and I both at the time had the same model Harley's - both Fat Boys and 80ci. I ran synthetic and he ran conventional oil. The oil temperature gauge in my bike was almost 20 degrees cooler than his during a road trip he and I took together.

lol..
