Hey, well sorry for posting this. Im a complete noob when it comes to all this but hey im learning... I tried to search and sticky but couldn't really find simple answer for someone who doesn't know what they are doing, what brand and such should I get for my S? Also I'm looking to put in synthetic, any downsides to this??? thanks guys!

 

10W30 Mobil 1. You can get 5qt jugs at Walmart for about $25. Good stuff.

 

As long as you are past ~10,000 mi or so, and you are not buring oil anymore.

 

Awesome! thanks guys!

 

this is what i use also.

 

I just now started using Schaeffer synthetic but it's kinda hard to come by. I buy it from a local dirt track racing shop. I got flamed in another thread for saying my opinion about it that it was the best. I knew it would happen. Try to find it though and you won't be sorry.

 

so your saying....you can feel the difference between different synthetics?

 

I use royal purple 10w30

 

Amsoil 10W30. The best oil you can buy IMHO. You can order it directly from their website. Takes about 5 days to get to your front door.
An inordinate number of S2000 owners complain of high oil consumption while using standard Mobil 1 (use the search engine to read them). Standard Mobil 1 is actually rather volitile (NOACK volitility rating is very high for a synthetic).
The popular fix for high consumption is to install the Krank Vent system.
If you're going to spend the money on a synthetic, you might as well get one that actually out performs a standard mineral based ("dino") oil. The only real world benefit of standard Mobil 1 over modern conventional oils is it stays fluid at very cold temperatures. Summer is just about here - I don't think you have to worry about cold temperatures for a few more months.

Amsoil or Redline would be my recommendation to you. If you decide on using a Mobil 1 product - Mobil 1 EP is actually a decent synthetic. It's more expensive than standard M1, but is a much better oil.

 

You're likely not going to "feel" a measurable difference between high quality modern dino oils and synthetics. It's a matter of how they shake out in standardized performance tests and chemical analysis.

I don't know anything about Schaeffer oils. I haven't seen analysis on any of their products.
I have seen a lot of analysis on Mobil 1, Amsoil, Castrol Syntec, Redline, as well as other major manufacturers - and that's why I use Amsoil. It's simply a much better oil. Redline performs very well - it's just more expensive than Amsoil.
