Syntec is not a synthetic, its a blend, in europe they are not aloud to advertise it as a synthetic as it is a CCMC E3 grade oil but for some odd reason they are aloud to advertise it as one here, wired isn't it?
Also with synthetic, if you have blow by (which allot of Mitsubishi's do) and get even 1% gas in to the oil it performs less then a basic mineral oils, my advice do what i did and switch to Rotella T oil, you can get a jug of it at almost any auto store and its cheap, checker has it right now for about $8. Any ways this oil if formulated to be able to take up to 10% gas and preform normal, it is a desil truck oil but it works 100% in gas cars. I should know i run it, and it states it on the back of the bottle.
Don't buy FULL synthetic unless you have a rebuilt engine, or your running 350 or more HP. Thats where synthetics really make a difference, in high strain environments.
NEVER! buy FRAM filters i was very pleased that you bought a wix, they are the best bang for the buck and the highest quality you can get next to the mobile 1 filter then its the k&n after that.
