1st oil change
 

I'm having my first oil change (3000mi) done this week. I've been browsing old threads, and the oil that seemed to be most recommended was Mobil 1 Synthetic 5W30, and a switch to 15w50 for the warmer seasons.

Does anyone have any input or contrary recommendations?

Also, if I take it to the dealer, hand them some Mobil 1 and say, "put this in there," will they give me any guff?

15w50 is better for cars like Scott's, where 70% of the miles on it are full throttle on racetracks and autocross courses. 10w30 is more suitable for daily drivers in the summer, 5w30 in the winter, unless subaru has added 5w20 to owner's manual. Then I would run that.

Dealers won't care what brand of oil you bring them, as long as it's the right grade and has the proper SAE requirements met. They won't flinch at the Mobil 1, especially if you ask for an OE filter, which I personally would recommend even if you change them yourself.

I used Mobil 1 exclusively in my RS, except for maybe 3 or 4 oil changes where I used Redline. Sometimes 5w30, sometimes 10w30. When it was totalled I had 106k on the odometer, and it was using less than half a quart between my 6000 mile oil changes. Most of that was probably blowby from the PCV system. And I certainly didn't baby the engine in that car from behind the wheel.

Sounds good. :idea:

Geh. I just realized that Kragen sells Mobil1 in 1qt bottles. The engine takes 4.2qt, so I gotta walk in with 5 bottles. Unless someone else sells larger quantities?

Walmart

Thanks - I'll take a look tomorrow. :disco:

Yep, Walbog's keeps 5qt jugs in stock usually.

I'm not convinced going to 10-30, or 15-30 in the summer is a good idea. I run 5-30 all year, track, autocross, etc. Walbogs is the cheapest. Beats costco, etc.
