B serious

I guess I got lucky in that my MY00 doesn't burn anything appreciable. Maybe 1qt every 3-5K. Track time, highway use, around town, doesn't matter.

I mostly use Castrol Edge 10W30. But I've used M1, Pennzoil Platinum, Castrol GTX (did 3 track days and drove from Chicago burbs to CA and back in summer time on the same oil lol), etc etc.

I have a bunch of GC 0W30 that I usually use in my TSX. I was planning on using that in the S2000 next summer to see how it goes. Be nice to have the protection of a 0W on start up...even in summer.

FWIW, I recently installed a B serious spec oil cooler. No change in anything.

I also have an vented catch for PCV and breather to prevent humongous clouds of smoke at the track

You really cant go wrong with either. When I was supercharged I used to run 5/40 for the better hot viscosity for the higher oil temps. 5w vs 10w is the cold flow ability. The engine runs effectively on both. It should come down to ambient temps in your part of the world and season and or if the car is left outside exposed or in a warm garage. these all factor in to initial start up flow ability and what you think is best. In the dead of winter with a car thats parked outside, 0w might be the best option, but I think in most cases 5-10w is sufficient.

306 miles, still on the top hash mark but it's dropped a little, I can tell because the little spaces around the hash mark aren't covered on the top half. So I'd say I've consumed about 100 ml in 300 miles. Not great but better than I've done with other oils. Usually I'd drop a full hash mark every tank of gas or 240 250 miles even with fresh oil. This may shear down and I may end up back to square one, but so far so good.

334 miles still on the top mark



At this rate given 5 hash marks and ~ 350 miles per hash mark that's a quart every 1,700 miles. Compared to 1,000 miles per quart, I'll take it. I just hope the syn blend will last 5,000 miles. I'll do a UOA at 3,000 miles to see what kind of life is left. Luckily the concept of winter is alien to me given where I live.

Same here. MY02. Zero observable oil burn between oil changes.

Well I'm pretty sure I'm consuming a hash mark every 380 to 400 miles. Which is roughly 2x as slowly as before, so in my eyes, this is a win. I'd like to run a pure synthetic, but 10w40 is hard to find, this stuff is everywhere for $6 a quart and I'll only need to buy 2 per oil change instead of 5 bottles @ $10 each. Granted it doesn't make a difference in the grand scheme of things, just nice to be able to go a gas tank and a half and not have to worry.

What benefit does having a higher W number give?
I understand what it means, but not sure why anyone would want/need to run a higher W number..

If the W is lower, the oil will run more freely through the engine during colder temps, then as the engine heats up, depends on the second number..right?

Yes. But I think that "high mileage" oils are effectively thicker at all times.

And maybe a thicker first number prevents some burnoff before reaching temp.

Sounds right...

I'd be more concerned about my engine not getting the oil it needs ASAP though..
I can live knowing my oil is lowering everytime I start the car from cold, but can't live knowing that every startup I could be causing more damage than necessary just to... save some oil..? just top it up!
