Engine oil RED LINE or OEM Honda
X2 on the Redline. I use this and i'm very happy with it.
They also have a race blend for better protection.
With Red Line you really have to look beyond the grade on the bottle. They will always recommend the thinnest kinematic viscosity oil because they have such a high HTHS.
The Fit is an awesome car. I have an 09 that has ~66k miles and NOTHING has gone wrong. Just the scheduled maint., oil changes (10-12k miles), and thats it.
Redline appears to be more interested in using the best additive package to make the best oil, not having to use pre-tested additive packages that may be geared more toward fuel economy.
The zinc and phosphorus levels (ZDDP) is much higher in the redline. Iron per 1000 miles is much better. Viscosity retention and flashpoint are much better also.
I love red line, search for my UOAs... i've tried most of the top teir vw502 approved oils in the FSI (Motul xcess, motul specific, total energy), and they don't even come close to touching red line with regards to longevity / performance.
4 qts Redline 5w40, 1 qt Redline w40 Race Redline blows away the competition... Lumps of ZDDP and Moly with the Race oil mix, fuel dilution pretty much disappeared, and viscosity/flashpoint are well within reason.
I would stick with a tested oil like Red Line 5w-40 or GC, but that's me.
Sticking with a single weight is a better idea than mixology IMO..
