Mobil 1 or Castrol Syntec?
Going synthetic this weekend. Hear a lot about mobile 1 , but was wondering about syntec since I've always loved Castrol. Any opinions appreciated. Also, when I switch how often should I do my oil changes? Thanks.

fart on a friends head!!!
this is true, im in the same boat you are in slippery. i love castrol and it takes quite a bit of work for me to not use it, but mobil 1 is by far superior to castrol syntec. it is still good, but not AS good.

I can't stand castrol. I believe thats horrible oil, IMO. I have used a lot of different brands. I find VR1 Valv. 20w-50 to be the best dino, and well a synthetic.....is a synthetic.

You might want to check Wal-Mart for Mobil1; the one near me sells 5 quart jugs of Mobil1 for 18 bucks.

Castrol Syntec is NOT a true synthetic. It's a highly refined dino oil that meets or exceeds the API ratings for synthetic motor oils.
If you're going to run synthetic, run Royal Purple SAE grade full synthetic. You can mail order it from Jegs (www.jegs.com) for under $5 a qt. They also make a race version which is non SAE and good for those weekend racers. Their head tech races a rotary, btw, so they have plenty of experience.

You can get Royal Purple at any Napa Auto parts store for the same price as Mobil 1. That's what I'm going to run once my new motor is broken in. RacingBeat has done tests on it and found it to actually increase HP. Here is a link to a thread I posted a while back.

Hey you all, Thanks for the great advice. It'll be royal purp. or mobil 1, for sure. How often should I change it though. My car is a daily driver, and has been for two years. I've always changed it every 1000-1500 miles. Certainly I should get longer life without worry.

By the way, as for Castrol, IMO its been the best for me in my past vehicles. I've tried them all, and upon inspection as well as daily preformance it was always the clear winner. But as I said, thats simply my experience. Thanks again for all the input.
