Hello all, I just received my oil analysis kit from Pennzoil and to my surprise I got Pennzoil Platinum High Mileage. I have a few questions...
There is no API certification logo on the front, should I be worried about that? It is SN rated but is the API logo necessary? The car in question is the one in my sig and it is waaaaay out of warranty.
Also, I have never used a high mileage motor oil in this engine and I never planned to. The dipstick is always up to the full mark regardless how long the OCI is. Any long term affects to using high mileage and then switching back to regular synthetic? It doesn't burn or leak any oil.
I'm excited about this oil analysis kit and I will post all my UOA's so you all can see them. I just wanted to get feedback if using non API certified oil is fine in my situation.
