I have gone from Mobil 1 to Shell Helix Ultra and the oil burns quickloy esp when you high rev the car. A lot of people who do not high rev the car have said that their oil level is fine. I have changed to Cusco 5W-40 and it doesnt burn as much anymore esp when you freq high rev the car.
You've got to keep in mind that most engines don't rev to 9000 like ours. It puts a lot of strain on the engine and that's why burning oil is a common trait among s2000's. The solution is quite simple really, if you plan on using a thinner cheaper oil, don't rev it high. Otherwise, use some good quality thicker oil. I use royal purple 10W40, it went from the 'middle' mark down a quarter between 'low and middle' after 5000 km's with pretty hard driving and one track day. Like people have mentioned above, solid changing intervals and the engine will last.
I'm considering trying Royal Purple 10W-40. All this talk about Royal Purple, so I thought I might try it... however, still a bit indecisive on whether I should go 10W-40 or 5W-30.
Engine runs good and the Honda Oil in at the moment is only 5W.... even though it's coming up to 100Km's, I might stick with 5w-30, or does anyone want to debate?
Guys please do not rev to 9000rpm, you achieve your max power and torque at around the 7000rpm mark!
Please use 5W-30 or 5@-40 if your engine compression is still good. Use 10W-40 for engines that are worn.
No point debating. Have tested the S2000 on my dyno and the power difference is there using a proper PAO 5W oil like Cusco 5W-40. I don't know much about Royal Purple as I have not used it but as long as it is 100% PAO, I will say give it a shot.
Currently have a S2k in my workshop that spun a bearing and worn piston rings. Hint hint: car has never skipped a Honda Schedule service and he brings his own Mobil 1 in for service at Honda. Please don't ask why? SAE has already answered.
