I recently mixed Lucas' into my oil but felt a major difference at the throttle. Today i changed my oil but want to know what everyones oil gauge was reading. Mine reads 30 at idle. Noone use that Lucas stuff. It makes your psi stay way too high. When I first mixed it in, my psi was almost at 120 at throttle even when i letet the car warm up for a good 3-4 minutes. What a junky product!!

 

mine is 30 at idle after warming up. What is the Lucas product that you are speaking of?

 

The first product on the page http://www.stadar.com/Lucas.htm

 

After some spirited driving mines at 15. Seems way to low to me. Sometimes its a bit lower like 13 or 14.
