Who can remember the NYC taxi study done years ago on different oils and additives in taxis that drove 24/7 for several years to measure (weigh engine components before and after 2+ years of severe service) engine wear ??? You can probably google the study... but the results were that additives did not affect (+ or -) engine wear.... Further.... as long as the oil was 10W-30 with the ASE burst on the bottle... all these oils performed the same. I can't remember Rislone for sure, but STP and others were a part of the study.

Choice of the proper viscosity (to me) would be in order. At your location I would choose 10-40 with some STP simply to provide the needed ZDDP(?) cam/lifter/rocker arm protection...

Originally posted by Bud View PostMy thoughts on this is not to add anything to the engine oil as I'm not as smart as the engineers at the oil companies. They design an additive package to use with their specific oil and adding anything to the oil can upset the balance of additives already in the oil. The best that can happen is nothing but lighten your wallet a bit and the worst could be long term engine damage. Any additive is a band aid to cover up a problem that should be addressed to make a permanent fix. If you feel that you need more ZDDP than what is in the oil you want to use, then I recommend finding an oil that has the additives you want such as Valvoline VR1, Brad Penn and most of the heavy duty oils such as Chevron Delo 400, Shell Rotella T, Mobil Delvac etc. Bud

Then there's also the little pellets you drop into each cylinder to "completely" rebuild the engine! I haven't seen them in many, many years but always wondered if anyone was ever taken in by that.Poet...Mystic...Soldier of Fortune. As always...self-absorbed, adversarial, cocky and in general a malcontent.

Was a Lubricant sales rep for many years. Our lab stayed on top everything that came along and while I won't say what there stand is, I used to tell folk that if there was and or is anything of value in various additives da oil companies would blend it in their brew. Just an opinion from old peddler,

Kamzack knows his S@#t!!! 50,000 miles with filter changes and 2 qts added on tow vehicle with oil sampling at 10,000 mile intervals made me a believer. i think Joe Hall might have had his tongue in his cheek, but to each his own. Really enjoying this Forum, keep up the good work everybody,till my ragtop project arrives i am on honey do duty!!! Doofus

I have an 05' Hyundai Accent with 341,00 miles on the original 1.6 4 banger. Runs great and burns no oil. Know what additive I've used? None. Just the factory recommended oil viscosity.: 10w40. I've used Walmart's Super Tech at every 3,500 mile oil & filter change. My 84' Harley FLT has 241,000 miles. I use Harley's recommended 20W50 oil and change it and filter every 3,500 miles. It runs great and uses no oil. Additives? We don't need no stinkin' additives. Routine oil changes with filter is all you need. Save your money!
