So you can break down your synthetic oil in 3k miles? Its your car but your wasting money.

From what I've read the 5w-50 was just to cover all vehicles across the nation in all climates under harder driving conditions. I run the same RP HPS, what made you switch?

I change at 5k right now but this is part of why I'll be sending in oil samples to be tested, I'd like to see what's left in the oil. RP and AMSOIL are confident in getting 10k between changes under "normal" driving conditions.

RP was one of my sponsors for SEMA, they gave me a case of 5w30 XPR which is their full race oil. I didn't see the sense in spending that kind of money to keep XPR so I stepped down to HPS since I don't race the car often enough to justify it. They use the same additive in both formula's.

How is it wasting money if the car gets driven hard and still runs like new? Would it do the same if I changed it less frequently? Maybe. Am I willing to find out? No. Oil changes are very cheap compared to the cost of a new engine.

Because most likely you would be able run it at least 5k miles before it needs any changing under the same conditions. The idea of 3k mile oil changes was true in the old days. Oil has advanced plenty over the years. Also check out bobistheoilguy.com/

I don't know if break down or contaminate is the correct word, but HPP says for those of us running E85 (especially since its more like E90 around here) should continue to change our oil at 3k miles. Even on E85, I went 5k this last time with no issues.

That said, my oil change was free at Grapevine Ford yesterday. They have a sign up that says they have to do a vehicle walk-around inspection and pop the hood with you present or your oil change is free. The guy got sidetracked looking at my tires that need to be replaced that he didn't pop the hood. Otherwise, it'd have been $60.

Haha, pretty cool that you got it for free, I probably wouldn't use that service advisor again though, he probably won't be too helpful, lol. I wonder if that came out of his check, do you recall the guy's name? My wife is actually there right now, they asked her why she brought her own oil and if something was wrong with the car.

McBride was the last name. Don't remember the first, maybe Todd???

With e85 yes I'd agree. It attracts moisture like a sponge.
