5W-50
Hey guys, I wanted to know if I can add Mobil 5W-50 synthetic oil in my S2000. I usually hit it up with 10W-30 but this person is recommending I put in 5W-50 for better performance and engine life.
Can someone please give me some feedback... thanks !

This is one of those questions that has been covered Ad Nauseam.
You may or may not be new to the forum - but please use the search. I just ran a search for "5W50" and pulled up several posts covering this exact topic. The search is not perfect, but it works.
Long story short: it's not a good idea. The S2000 is designed to run oil no thicker than a 5W40 - running an oil thicker than 5W40 may very well starve critical components of oil just when they need it - at high RPMs (and temps).
If you want more details as to the whys and hows - the search is your friend.

This "yeah I'm using a 50 weight on the track because thats better because the engine gets hot" will only be partly true if the engine actually reaches those high temps for a longer period.
And I think it doesn't.
If it does you have other problems and you can't solve them by using a thicker oil.
And.. even driving like a granny the oil that gets sprayed underneath the pistons gets pretty hot - for a very short moment.
No problem at all.
A xxW-50 oil is too thick for the F20/F22.
The F20/F22 doesn't need it and it was designed with xxW-30 oils in mind.
Going FI without an oil cooler you might want a xxW-40 but thats about it.
And I think it doesn't.

I was told by an engineer for Honda that the cars is designed for the recomended weight for a reason . The recomended oil weight best suits the engine in the car as well as the perfomance it is designed for . The problem with ging with a thicker weight is that you starve the engine of oil in areas it is more difficult to lube ,most vital being the bearing journals

Thanks a lot guys. I think I'll stick with the 10W-30.
Im in India and to my knowledge its the only S2000 in the country. Temperatures do go high (40deg cel) during the summers but its the winters now and it varies between 20deg cel and 30deg cel... and i think the regular 10W-30 should do the job.
Thanks once again.
