Razor · 12-19-2002, 01:53 AM

well, i am planning to change my oil sometime this week, and i went to kragen to buy the filter and oil. I asked the person working there which one is better... 10w 30 or 10w 40, he said that when your car is over 100,000 mi, that's when you use 10w 40, but under taht 10w 30 is recommend...

We use Synergyn or Mobil 1 at the shop.

10w30.

I use Castrol RS 10W60, anybody uses it too?
The RS is the top of the line oil from Castrol, it is normally used in racing cars.

Never heard of 10w60, but 60 is far too thick for a 4g63.

That's what I was thinking.......why not just stick to Mobil 1 10w-30?

It is an oil normally used in racing engines and it is not very expensive.

How much does Royal Purple cost? And, where can I get it?

SPEEDY · 01-01-2003, 09:57 AM

I normally change my oil and filter every 2500 miles, and I usually use M1 10w30 fully synthetic with the oem oil filter. Although I have just recently switched over to M1 15w50 to try it out.

DSMTommy · 03-02-2003, 03:15 AM

Royal Purple = Ebay - great price

laserRSawd · 03-02-2003, 10:26 AM

What do you guys recommend me to use after a rebuild? Should I break it in with regular oil and then switch to synthetic? If so how long should I run regular oil in it?

austin · 03-02-2003, 03:59 PM

Yes, break it in with conventional oil, then flush and replace with synthetic if desired at your next oil change.

Keaka26 · 03-12-2003, 01:48 PM

the general idea is to break in the car using conventional oils to let the rings seat properly, but Amsoil claims you can break in a car using their oil with no problems. I might also mention that the new evolution as well as C5 corvettes come FROM THE FACTORY running full synthetic Mobil 1...what does that tell you?

And just because a car has high mileage, does not mean the car will leak when changing to full syn...I switched to full synthetic at 119k miles, and not a single leak.

I wrote up a comparison on some oils that you guys might be interested in, check it out at www.fattonyracing.com ....go to the "product reviews" section (needs to be renamed) and go to the oil comparison...I will be an Authorized Amsoil Dealer soon, and I will be most likely offering a discount to DSM owners if anyone is interested.

It's not a rule of thumb that all high mileage cars will leak with synthetic oil. However, if your car has a lot of carbon deposits on already cracked rubber seals and gaskets, then yes, synthetic oil can break down those deposits and cause a leak.

Keaka26 · 03-12-2003, 08:11 PM

agreed...but the mileage and regular wear and tear itself wont cause oil leaks when switching to synthetic...as long as maintenence is not abused.

notracing · 03-13-2003, 10:02 PM

I have a 90 N/T with 148K, I never had a smoking problem until recently. This is only the third time straight that I used Mobil 1, and now it has developed a little smoking condition, but other then that I like Mobil 1, the car runs great.

I got hooked on Mobil 1 when I had my SHO 3.0L

RedTurboEclipse · 03-13-2003, 11:27 PM

rivet0r · 04-25-2003, 09:15 PM

Just curious on what oil I should use.. do for a change pretty quick, and I've had the car for about 2 months. 90 Laser RST.. Thanks again.

jd1828af · 04-25-2003, 09:41 PM

i use castrol synthetic blend but i would go with mobil 1 if you got the money. just stay away from penzoil. valvoline is also great if you are on a tight budget.

SetH · 04-25-2003, 10:41 PM

Royal Purple or Mobil 1 synthetic

igs · 06-03-2003, 03:01 PM

pennzoil 10w30 dino

Keaka26 · 06-03-2003, 10:54 PM

Sweet jeezus, it doesnt get any worse than pennzoil. Theres a reason why most speed lube places use it. And thats because its cheap. And you get what you pay for. Cheap oil. Every engine ive seen that runs pennzoil has a thick layer of crap all over everything. Awful.
