I've been searching through a lot of forums and information regarding Accel Brand oil. For those unfamiliar its SF grade, in 10w-40. The spec sheet from Warren Distribution(owner) states it has 1100ppm of Zinc and 1000ppm phosphorus.
The SF is the part that worries me. I have a 1972 Cutlass with a Rocket 350 motor and I'm looking to replace the needed Zinc for the flat tappet cam. It's not an ultra high performance motor, so the boutique oils like Brad Penn just aren't going to happen. On the flip side, the 2.5x price tag per quard of the Accel Brand worries me too. Decent oil for less than Super Tech(Walmart brand, also by Warren Distribution)
If it's branded SF can anyone still check up on it? Or is this a way for Warren Distribution to sell junk oil using cheap base stocks, and get away with it because it's "outdated" and can't be monitored. I usually do oil changes between 2500-3000 miles anyway, so I'm not to worried about sludge with the SF grade. Used Mobil clean 5000 for a long time, and recently switched over to Quaker State. The defy being a semi-synthetic will probably clean out too much and I'll have problems with leaks, etc.
I can't see, to find a spec sheet for the QS High Mileage that lists the Zinc rating.
