Same here with a ZDDP additive.

The owner of Pure Power told me to run Delo 400 15-40 !! Said it has all the good stuff still in it... but to NOT run the LE (low emissions) as it has reduced levels of the good stuff (zinc and manganese etc).

I use his filters -- they filter 100% of your oil with a cleanable SS mesh filter... they're "expensive" --- but so are all the parts INSIDE my motors...LOL

The diesel grade oils are supposed to have more of the better additives than regular "gas" oils, although they are reduced from what they used to be.

I was kidding about the Wally World oil. I run Valvoline VR1 20w50 racing oil when it's above say 70 degrees and will go to a lighter weight in the cooler months.

when it's 70 here, it is the cooler months. :lol:

You're preaching to the choir. It's going to be 112 here Friday! My car is in hibernation. I'm going to be hanging out at the pool or lake drinking and ice cold beer on Friday instead of driving my car. :unibrow: Not all bad.

..but that's a "dry" heat :rofl:

Actually it does make a huge difference buuuuuutttt 112 is just ridiculous. 100 doesn't phase me anymore.

Same here. Come to think of it, I've never blown a motor so I guess it works, LOL.

try 105 in the rain... :thumbsup:
