It'* more important to watch the color of the oil. Oils job is to of course lubricate. But it'* also there to remove particulates, such as soot. That'* why it turns black. It gets to a point where it can no longer suspend the soot and your engine starts to sludge up. Rapid oil changes are the only way to keep the insides clean.

The oil test I was trying to load here a while back is biased. They did the same test with Head & Shoulder Shampoo and made it out preform all other tests.I've been looking around on the web and found out about the TEST Oil is Oil?? I went to the Royal Purple site and was doing some reading of the question and answers section.One of these days I'll probably switch over.

Ran the old 3800 in my Regal to 217k mile on conventional oil. I overheated 4 times one summer and the motor got effectively destroyed. I had tried a variety of synthetic oils including Royal Purple and they all felt the same.

I use valvoline 10w-30 in bubba and thats a 383 stroker motor valvoline has been his favorite sense the engine was built side by side with a wix racing filter at 3k mile oil comes out clean.but if there is one thing i never forget is to change oil every 3k miles.I just did an oil change on my dads truck using 10-30 synthetic and his truck seems to like it .
