GF-6 is the new standard, started in may, designed to mitigate a lot of the problems associated with small direct injection turbo engines, GF-6a is backwards compatible for most weight.weights, GF-6b pertains only to the 0-16 oils primarily for hybrid vehicles.I generally see SN plus but not GF6
Yeah, well....Yes, change your oil at 5k intervals, use a GF6 certifed synthetic, use Toptier fuel and avoid short runs in cold weather. My Blackstone Labs oil analysis are showing under .5% fuel dilution using this protocol.
I deliberately put in 4 quarts that oil change, so it was at the top of the dipstick the whole time. So far this interval the oil level does not appear to have risen, so we will see if the dilution is any lower.How high does your level on the dip stick show ?
