Maybe for others.
I'm always trying brands, same with detailing.
There is always something better

well i can say dont try nulon lifter quiet stuff put it in westerday run the car and the lifter s**t itself 5 minutes later sounds like a worn out diesel so one brand tested ,ordered new lifters for $14 each

thats right dude.....
changinf brands and type of oil all the time is asking for trouble

I think Nulon Stop Smoke is a load of crappola, every morning i start my car and theres an all mighty puff of blue smoke out the exhaust. Yum... I need a 'Replace Engine' additive.

Im a fan of changing the oil every 5K rather than additives - keeps it clean as a whistle....but the old man swears by Nulon Preforamance treatment. He loves telling the tale of when he was pulling his caravan in his landcruiser, and the engine started making strange noises about 50k's out of the next town...so anyway, he goes to the mechanic when he arrives and the dude says that his sump plug had fallen out and there was no oil in the car - but the engine was fine! Just some minor work needed and he was away. True story (or so he keep frickin tellin me)...

only once in my life did i use cheap oil when i had a holden and 1 day later it thew a rod that was fun then once in my life i use an addive and the lifter craps itself theres a lesson in there .
