I have 97 LX 450 with 150k on it, i been usin 5w-30 & 10w-30 for 7 yrs also i do oil change regularly by myself around 3k or 3.5 , imean logically oil is oil once got into piston rings mixed n burns. No matter how damn good the synthetic is dont rely on or believe that oil can make u feel better by stayin lil longer.(dont need to get oil change soon) :whistles: The longer u wait to do oil change the faster & sooner u gonna ruin that motor.

I have 97 LX450 with 150k on it mostly highway driven state to state ~ NYC to LA My big concern will the motor still be able to hold up with another add 60hp? Or should i have major tuned up with all the pistons & rings? Really big consider on this because its not cheap at all... to readjust all the them. By the way, right now my LX 450 motor running perfectly fine.. i had all the Synthetic oil all over since i bought the car brand new 7 years ago.. :P Mobil 1 10-30 ~Motor Oil Mobil 1 75-90 ~Gear Diff lubricant Mobil 1 Syntheic~ ATF fluid please need professional advice & suggest on this, thanks
