I am wondering I am going to be doing my first 1K mile oil change next week. In about a month is my first autocross event. We will still be getting into the 20, and 30 for a month or two more. I am just wondering should I still run a 5w-30 when doing autocross? Or once summer hits should I change to a different weight oil because of autocross and being on a track with temps in the 90+ area?

This is my first turbo car so I want to make sure I take car of that engine just right.

5w30 is fine for autox. Auto-x is more or less running at speeds no higher than highway speeds, and for only short amounts of times (around 1 minute per run) and then the car can cool off usually between runs. You'll be just fine. :)

which oil? please don't say rp or m1.

I have not picked yet. I am still running on the dealer oil. I am thinking of getting quaker state.

i think that's the first time i've ever seen quaker state mentioned on nasioc.

which oil? please don't say rp or m1.

i ran m1 5w30 starting last summer with a few auto-x's, and I had a great UOA:

So yeah I had no issues but it's up to you.

5w-30 is what I run, on the street or at the road race track

I've run Mobil 1 on track days with no issues.

Are you running M1 dyno for full syn?

Not to start another oil war, but the Shell Rotella-T Synthetic 5w-40 is friggin fantastic in turbo Subarus and is cheap to boot. Wal-Mart for about $17/gallon or most Advance Auto Parts, VatoZone, etc.

^ that's what i was going to recommend. some have good UOAs with m1 but there are also many that have spun bearings while using m1 and rp. that's enough to scare me away. fwiw, i've been using castrol syntec 0w30 euro formula for the last 2 oil changes and have had little to no oil consumption.

also, castrol syntec is on sale at autozones. $29.99 for 5qts and a k&n filter.

i always use quaker state. although im on penzoil for the last 1500 miles and may engine seems a little noisier. Im going back to quaker state horsepower!

Full synthetic mobile 1,

ive used both of these as well and in my crawford s2 block i use like 2-2.5 quarts every 3000 mi....am i burning too much? did a compression test at it was 143-145 across the board

Full syn.

Ran mostly M1 syn and Castrol GC without ever losing a drop, 1 day on RP and I spin a bearing, coincidence? :alien:

I've been running Mobil 1 5W30 for last 30K, including 2+ years of AX. Blackstone oil analysis shows less than average wear.

i would go with castrol syntec love the stuff works great

+1 that is all I use

I've run Mobil 1 Full Syn for 5 years of autoxing and daily driving in my WRX. 56,000 miles and no probs.

+1 for the 0w30 "german" Castrol, or the 5w40 Shell Rotella stuff from Wallyworld.

um..i'm going with yes. i think i'd **** myself if my engine was eating that much oil every 3k miles.

if i had the same amount of money invested, i'd try switching to the shell rotella 5w40 or castrol syntec 0w30 euro formula.

^^^ or Amsoil 0w30 or 5w30

What is so good about Shell Rotella-T Synthetic? I did searching and it looks like it is not good if your car still has a cat on it.

i use like 2-2.5 quarts every 3000 mi.

Anything under 1 quart in 1000 miles is considered acceptable. If you want to subaru with a new car and that kind of consumption, I'm not sure they'd do anything about it. Built motors with loose tolerances, I'm not surprised they have consumption issues.

I wouldn't use ANY 30 weight oil in our motors. I currently use 0-40 eurospec M1 and will probably be using 15w-50 for this next track season. The owners manual's pretty clear that for severe service you want a thicker oil. Autocross and track use qualify as severe service in my book.

Motul has gotten affordable when compared to M1. Guess what I've switched to. :D

Here is a tip - use clean oil - the rest is really not that important as long as it is with in the ratings in the owners manual.

100% agreed. We let internet forum madness believe some stupid stuff sometimes. End of discussion.

I got Shell Rotella-T last night. I went to wallyworld for it. They did not have any large jugs in stock. I paid $6 a quart. It was the only 5w-40 they had in stock. I am going to stop at anouther walmart to see if they have it larger ones. I am going to check a few autoparts places. The walmart I went to they only had 5 quarts in stock so I picked up it up. If I find it cheaper I will return what I got last night.

I run 15W-40 Rotella T with Triple Protection in my wagon. I autocross frequently. Using the 40 weight; I noticed considerably less blow by. That is, I don't have to top off the oil between oil changes anymore.

I live in Vegas, so I'm never have to start her in temps below 30F ~ -1C; the 15w is just fine for me.

I might be able to go to 15w in the summer. Right now I still have to worry about start ups in 10-20 deg weather.
