Propilot said:M1 is yesteryear's technology. The stuff that Pennzoil and Quaker State are making from natural gas is state of the art and what I run in mine.
Quaker State and Platinum are available in 5W-50
todcp said:Quaker State and Pennzoil are the same company these days. Owned by Shell Oil. All make great products.
Grant 302 said:Neither of those are made from a GTL process from what I found, and the quaker state data sheets says, "• May be used for Ford WSS‐M2C931‐B (SAE 5W‐50)" but not "Meets or exceeds Ford..." like many of their other grades.
Are you using a different grade of oil than 5W-50?
Propilot said:Pennzoil Platinum and Platinum Ultra are both using GTL technology. I use the Quaker State Ultimate Durability 5W-50 as it does meet the Ford Spec.
And yes, Quaker State and Pennzoil are owned by Shell.
Grant 302 said:Okay, so the Quaker state isn't GTL in 5W-50 and the Pennzoil Platinum 5W-50 is a full synthetic GTL blend? The 5W-50 isn't available in 'Ultra Platinum'.
SeattleBoss said:NAPA has Mobil 1 for $6 this month. Just bought enough 5w50 for the year at considerable savings.

I got a gift card from a friend for Advanced Auto so I thought what the heck, I'll see if they will match the Napa sale. Long story short, went in the store, they said they would match the price, 30 minutes later walked out of the store with nothing. Horrible manager who disappeared and in the end they said they couldn't match the price. Called Advanced Auto customer service and they said that was incorrect, they will in fact match the price if they can verify the sale. Best way is to bring the add in or they can call Napa to confirm. After that debacle and waste of my time I'll get it from Napa even though it's further away. I am all about customer service even if it means spending more because I am treated professionally and I admire people who take pride in and are good at their job. Ok, done ranting
