My last thread enlightened me to the new GF-6 standard. Went outside and checked the two jugs of penzoil plat i have in the garage and both are GF-5 compliant.
I usually order my oil online, and sometimes you never know how old it is. Is there a way to tell, for the Penzoil for example, if it is the older GF5 or newer GF6 oil without seeing the back of the actual bottle?
my new (to me) direct injected truck would prefer GF6 oil i believe. Maybe i just need to buy at the local parts store for the first few oil changes and confirm with my own eyeballs?
