You just called your brother an idiot. That makes me diagnoses the failures as human caused, not oil-caused.

We've never had an oil-related failure on this Forum with over 7000 brain-equipped members.

I agree with the Royal Purple scam call above. Find me a 3800 with an oil breakdown related engine failure. That's a challenge.

I'll keep my Mobil1 at 5000 mile intervals.[/quote

iF ROYAL PURPLE IS A SCAM SO IS MOBIL 1 I GUESS? ;) IF THERES NO OIL RELATED BREAK DOWNS WHY NOT JUST RUN VALUE TECH OIL FOR 89 CENTS A QUART INSTEAD OF MOBIL ONE?

Napaman, Royal Purple's PRICE is a scam. Not the benefits of synthetic lubricant, which many of us run.

Please stop using all caps. It's like yelling on the internet. ;)

Im not being a 'brainiac', I just didn't think that since other than the fact that synthetic is man made and has more detergents that it would actually increase HP. And you can tone down the attitude a little bit.

FWIW, I run only AC Delco PF47 or PF52 filters (can be found anywhere, are very reasonably priced, and always seem to do well in oil filter tests). We use royal purple in the '02 GTP and it gets changed every ~5k miles or so. I run the Mobil 1 "clean 7500" or whatever it is in m GT, it is the synthetic blend stuff. I am kinda paranoid so I change my oil every 2500 miles or less (never more) so I don't see the need to spend $5+ a quart for full synthetic, I would run it if I didn't change my oil so much. Plus usually I do work to the engine more often than I need an oil change and I end up changing it before I need to anywas. I used the run the valvoline durablend but the Mobil 1 is cheaper....lol. We use valvoline durablend in the SSEi and have since day one. It gets oil changes when the DIC says to do so and since its all highway miles that is usually every 7-8k or so.

FWIW, I just poured 5 quarts of that no name brand oil in my engine today. But I just had it torn apart and it will be getting a change in like 100 miles....lol

I run Mobil1 for 5000 miles. But the only reason I do is because I had a pair of UOA's run to prove it had less particulates and breakdown than typical dino juice at 3000.

I don't think anyone can truthfully claim Royal Purple produces RESULTS any differently than any other synthetic oil on the market, particularly not enough to justify that price. :lol:

so mobil 1 5000 and an ac delco filter is the way to go? Not my fram filter from walmart and castrolGTX :cry: :D

If you're running a Fram, you didn't do your homework. :?

I don't run Mobil1 5000. I run the traditional Mobil1 FOR 5000 miles.

With a K&N oil filter.

Yea i was just reading about the fram filters looks like they suck bad. I think my next oil change will be k and n filter and mobil 1.

Dudes? all i was doing was making a suggestion that i thought people would like to try and immediately criticized and your telling me to tone down? I never knew i was yelling, im just typing? ;) Royal purple is 50cents more than mobile 1 if you go to the right place and like i said before, i garuntee hp gain and a smoother running engine.
