I just used my last free oil change so I'm going with Royal Purple on my next one and probly the rest. I do no Highway driving and It is bad on a car. So $45 is worth it. I have under 10,500 and have had it since Dec. 04'. Low miles is a good thing, but all in-town miles isn't. 1/4 mile here and a 1/4 mile there is bad on a motor.
I'm gonna use my 3 free OC's. Been using M1 on Honda's for years. But I hear over at "Bob is the oil guy . com" that German made Castrol Syntec is the s**t. I have been looking and have been unable to find any though...only US made from imported stocks.
Just a little info for you guys wanting to use Royal Purple. That oil is actually a racing oil and does not meet SAE standards for the auto industry. If you ever had an engine problem and the dealer knew about that oil being used,you might run into warranty issues. Don't get me wrong,I think Royal Purple is a great oil, but they just have not gotten around to getting certified for street use. I guess it costs millions to get certified for the first time....rumor I heard. Redline oil makes a great product that IS certified from the SAE for street use. I use their synthetic gear oil which I changed over at my first oil change...3000 mi.
I use Mobil1 5w30 with a Mobil1 filter....I'm changing back to the stock Toyota filter next time around though...the Toyota one is a better built filter.
Amsoil. This is the stuff. I've been using it for a few years, first with my diesel pickup then in my toaster and an old Toyota pickup. Gotta love the change interval, too! I never used any of my free dino oil changes since I'm so familiar with the superior benefits of Amsoil (no, I'm not an Amsoil dealer!).
