90crvtec... Sorry I'm asking questions and I'm only a month old! lol.... anyway I'm at work and doing some ninja posts so sorry for the misspellings hehe. Its just so many people on here and other forums for the s2k use different types. I even saw some people use heavier oils like 10w-40 or something like that. I'll probably switch back to 10w-30 MOBIL (hehe). Thanks for the replys by the way.

 

That's the problem with threads like these. Everyone responds with their own OPINION, not fact. So you will see some people run some really weird oils (5w50, 15w40, 0w20, etc. etc.). There's also a lot of fuzzy logic and brand slinging that happens in threads like these. So people will jump in and tell you to ONLY use Redline, or Mobil, or Shell. Other than what the manual states, it'll be impossible for you to choose the best oil for this car without doing some extensive research and doing your own UOAs to see what your particular engine responds better to.

Conversely, if you were to buy the cheapest oil you could find that still met the factory specifications listed in your manual you'd get bored of the car before you had an oil related failure. And if you think that the dealer won't fill your crank case with the absolute cheapest bulk oil that they can find then you're in for a nasty surprise.

I'm not trying to bust your balls here but threads like these are kind of like asking "what color of car should I buy?". Everyone will have a different reason for suggesting a different color. If the oil journals prove anything its that there are a lot of great oils out there that don't cost an arm and a leg, use any of them with confidence.

BLACK IS NOT A COLOR!!!!

If anything, it's all about that Laguna/Bermuda Blue

 

blasphemer! Burn him at the stake!

 

In the past I've read a few of the UOA's. Can anyone really make heads or tails of exactly what is being said.?
It seemed to me that the oil being tested had variables in effectiveness at various milage intervals.
To paraphrase a little, a certain oil that started out as excellent dropped to good at 3k then jumped backed to very good at 7K and then continued to improve to 10k with peaks and valleys inbetween or something to that effect .
Interesting study for petrolium engeneers maybe, for the rest of us probably not so much.
Perhaps the future will be a little more precise.

 

ok then what kind of oil is everyone using?

and when do you recommend an oil change on a new car..

only 10mile now.. but want to be prepare

 

Its strange (to me at least) that I haven't seen anyone mention redline synthetic oils.
They are a true synthetic and seem to be pretty highly rated.

I just switched from regular 10w-30 dino to 5w-30 Redline synthetic .

I've had great success with it on my RX7 so I shall use it on the S2K

 

After reading the oil journals, and conversing with XViper, I chose to keep with good dino 10W-30 until the car hit 10,000 miles, and thereafter use Mobil1 10W-30. I change oil at varying intervals (varying by how many track days the car has had since the last oil change), but I never go more than 5,000 miles between oil changes (and when I tracked the car, I often would change at 3,000 miles or less).

From all I have read and seen, if you change your oil and filter regularly (and 5,000 mile intervals with Mobil1 qualifies), oil will not be your problem. And since it takes me about ten minutes to change oil, there's no reason not to do it regularly, even if it's overkill.

 

I'm also attempting to stay reasonable. Regular oil until 10k then a perminent switch to synthetic.
