Quaker State with Napa oil filter. I buy the cheap stuff.
Oil is oil.

...with apologies to Captial One.
I'd like to know what oil y'all are using. You know, conventional or synthetic, what weights. That kind of thing. I've thought it interesting my 1.8L MG calls for 20w50 and my 2.0L Zetec calls for 10w30.
If it wasn't for this forum and all its fine participants, I would have gotten so frustrated at this car and gotten rid of it. Thanks to y'all, I want to try to keep it running forever!
Well damn, you're right, it has roller finger followers. I stand corrected. This is also the only engine I own that I've never had apart. Doesn't matter, I'm still going to run an oil with a ZDDP formulation, makes inventory management easier when you're keeping four cars on the road. I've seen too many cams and slider followers with excessive wear to trust the EP formulations in modern, SM rated oils.The Duratec IS NOT a flat tappet engine. It has roller followers. The reduced level of ZDDP in API SM oils has been compensated for with other additives. It will only be an issue on flat tappet engines WITH HIGHER THAN FACTORY VALVE SPRING PRESSURES.
Since I have nearly 190k miles should I be looking at Maxlife or a similar high mileage formula?:shrug:

and the 99 cougar has always run 5w20 mobile 1
...So dont use an EP oil then. And by seen I assume you mean you've heard people talk about it on the internet. SM hasnt been around long enough for any single person to have much experience with multiple damaged engines.
Thanks, Big Jim, for setting me straight on the correct oil weight. I don't have a manual on my Zetec (yet) and have just been using what Prolube put in. Since I have nearly 190k miles should I be looking at Maxlife or a similar high mileage formula?:shrug:
