But on the real seams you may need New VVTI cam gears.

No added mods i was going to add headers and tune actually.

The 0w-20 stuff is for fuel economy...
I would run something like Motul 300v.

I normally run motul 300v 5w-30 its great stuff but its also liquid gold $$$, right now my budget is a bit low so i just ran some mobil 1 5w-30. Im purchasing some motul from CS Garage soon so my next oil change will be motul.

This
, specially in TX where you have to take into consideration the extreme heat we get and add on top of that that i do events from time to time.
What to hear something funny, tonight i was driving the w210 E-420 when my wife and i started to feel the engine run weird and loose a bit of power, no code but it sounded like it was misfiring. As soon as i got home i was thinking a bad plug, or coilpack. Since i know this car inside out since ive had it since 1997 i checked plugs and coil packs one by one and found cylinder 4 was misfiring. I took out the plug and noticed it was a bit loose and found the inside to be soaked as well as very dirty. Cleaned the plug and coilpack put it back in the car and voila no more misfire. Next thing you know im going to start to misfire
.
Im praying the issue with my FR-S is as simple as it was with my w210 tonight.
Pics of the issues with the w210:
The culprit:
Left coil pack soaked
