I recently had a used motor swapped in my 00' ranger after overheating and ruining my old one with 139k. This is actually the 4th motor since all the other ones swapped in were bad and luckily i bought the warantee from the shop who did it so it was all covered. This one runs good and the powers all there. It seems a little noisier than I'd like it to be(engine noise not exhaust). It sounds more like piston slap from what other people tell me, not like valve tick. I'm using 5w30 non synthetic penzoil right now. I'm just wondering if another oil would be better, or if lucas oil stabilizer would help? I have read many many negative reviews of lucas oil additive but I think most are just repeating what they've read of bobistheoilguy saying it foams up and shit. I do live in IL where temps get to near 0 every week this time of year. Any suggestions would be appreciated thanks!
 
If it truly is piston slap, I'd have the motor looked at from the shop under warranty. Who are you getting these engines from? The 4th motor under warranty seems a little odd. In my personal opinion pennzoil sucks. I have run castrol gtx for years and have had very good results.
 
well its the junkyard or parts recycler that keeps giving my shop the motors. Obviously since we've already paid them they lose more money on each motor they give me so im pretty sure they aren't obligated to give me the best motors they have anymore.
 
According to the American Petroleum Institute, BOTH Castrol and Pennzoil are fine oils.

ALL oils are good oils. If one or another brand caused breakdowns the word would get around and we'd ALL know which brand was bad.
Instead we have all brands made in the same companys, which bottle and ship every brand of oil. The oil is no longer from the fields of the north and west but it is from the closest field to the bottleing company!
So no matter which oil you think is best they are ALL THE SAME!
