You got punished for going to jiffy lube [}]xbox4414 said:
this will be the first time I've done my own oil change, so i went threw my receipts from Jiffy lube and i noticed the dumb asses have been putting in 10W-30 Mobile1! Shouldn’t they have been using 5W-20? Can them putting in 10W-30 hurt my car?
wrong. clearnces are much tighter on new ford and honda motors. 30 weight will have trouble getting under all bearings and such. motors keep getting built tighter and tighter...EricR said:Hard to say.
The "-30" part isn't a big deal. Ford and Honda have switched from 5W-30 to 5W-20 in the USA for reasons related to EPA fuel mileage ratings (the crank can cut thru the thinner oil easier and thus gives slightly better MPG). In other parts of the world they still call out for the 5W-30.
wrong.EricR said:Why then in countries without active EPA concerns does Ford still recommend 5W-30 for Duratec engines? The same is true with many of the new honda engines.
Plus, many ford dealers haven't gone to the expense of adding 5W-20 tanks and lines onto their bulk oil handling systems and routinely fill these new engines with the 5W-30 they have been using for ford engines along.
The 910 has been the Duratec filter since 2003. I don't know why or when the 793 came into play.313-Matt said:
Now because the idiot at the parts store couldn't tell me the filter, I went to check Motorcraft's website. They list two filters - the FL 793 and FL 910. Now I clicked around and could not find which was best. The 793 has been around for a while, and the 910 is the (05-06) Ford 2.3L only.
Anybody know the answer to this?
