Subject: Re: Engine oils - Brad Penn, Royal Purple, Mobile1 by Josh on 2011/2/28 22:20:01 www.bobistheoilguy.com is the best website/forum I've found for oil related questions. Nearly everyone bases their opinion on some X factor, almost no one takes the time to actually do an oil analysis and make decisions based on real data. It's always, "I know this guy who lost an engine because he used QuakerState on the circle track... I won't use Quaker State because of that." Who the hell knows why some redneck lost a motor, it could have been a thousand things other than the oil. "My cousin took apart a motor and it looked like the rod bearings had machined the crank surface... He was using Mobile 1, so Mobile 1 is junk." Almost everyone has some bull shit story like that has guided them to one brand or another. There was a guy on here years ago, Casethecorvetteman, he was like that. He swore up and down that Royal Purple was junk and that Castrol was the best motor oil available. When asked about oil analysis, he admitted that he had never taken the time to have it done, he was basing his opinion on some engines that he had seen torn down that were using Royal Purple. He didn't even lay a micrometer to the parts, his entire opinion was based on data he acquired by LOOKING at some parts from a distance. He was willing to e-fight to the death on oil because of something he never touched or measured. I don't know your builder, but I would be very surprised to learn that he is basing a recommendation for you on oil sample data. Most shops that I have experience with use an oil that hasn't directly caused them any comebacks. I would trust the builder on viscosity, since he set up the bearing clearances, but on brand... Do your own research. Doing your own research on it doesn't mean you won't go with your builders recommendation, but being informed can't hurt. Oil analysis is cheap, $10-$20 at nearly any heavy equipment place. Dropping off a sample of your oil on the first, second, third, fourth, fifth, sixth, etc... oil change and looking at the data will tell you if you are making the right choice. For $15, there's no reason to keep guessing. |
