I’m anASE Certified GM Heavy End Mechanic…I’ve R&R’d so many engines and from MY EXPERIENCE…engine that have had pins oil in them or one of the biggest failing engine engines. Lots of scoring lots of metal shavings pins all its terrible oil. The next terrible oil is Quaker State. Do not use either of those. I’ve torn down a couple of engines with mobile one. One of the main reasons for failure on AFM engines is waiting too long for oil changes. If you will change your oil at 5000 miles with mobile one you will never ever have an engine problem on an AFM engine. STP oil treatment is one of the greatest things ever invented. It contains ZDDP. The MAIN function of ZDDP is it costs critical engine parts and provides a very slight coating on all your engine parts eliminating wear…this is EXTRAORDINARY for AFM lifters and cams…. ALSO, THROW THAT PENNZOIL AWAY!! That is the WORST OIL you could possibly use…might as well put 8 quarts of water in your engine…secondly, Lucas Heavy Duty Oil Stabilizer clogs oil pumps. use Mobil 1, 0/20W oil with 2 bottles of STP Oil Treatment, change your oil every 7500-10,000 miles, DON’T DELETE just change your oil BEFORE IT BECOMES DIRTY AND THICK and you will NEVER have an engine issue.
