would you guys say Motorcraft is the best oil for a Mustang? Like over Havoline... Mobil 1.... all the others? I'm using synthetic, and right now it's Havoline, but a good friend of mine, who's in the Auto industry says ''motorcraft is made by Ford, for Ford, and it's the only thing that goes in my Ford''... But I don't know. Does Motorcraft make the best motor oil for a Mustang? It is a racing car. Mobil 1 is a racing oil.... NASCAR shouldn't be all that wrong.

Ford builds cars(engines), Nascar builds them better and for racing, go with what you think.

Ford (contrary to the belief of some idiots does not make ANY motor oil) Motorcraft or otherwise, they simply take bids from different oil companies and buy from the lowest bidder. All oils must meet current specifications of SAE or they cannot be sold, they can be better, but they must at least meet these specs. SAE Society of Automotive Engineers. One oil, dino or synthetic must meet the same basic specifications, as any other. Basically its whatever brand you prefer. There is also a letter which delinieates the current or which ever SAE approval the oil has such as SAE-J or otherwise, I am not sure what the current letter is, but you should check for the current approval letter as some discount stores have been known to sell old oil.

:disgust: Quaker State and a few others that used PA crude oils used to get a real bad rep around here, and from all I have seen they deserved it, apparently that crude has a waxy base, and when they make motor oil with it, it coats engine parts inside your car in a black waxy residude, I have seen engines torn down with about 1/4 inch of that crud all over every thing inside them.

This was from a past posting of mine

Here is something to think about . The saying you should not switch brands of motor oils was true at one time. Some Oil companies used wax based products in the oil to make it viscous (thicker). Not a good thing!!! So changing it around 3000 or so miles is good and wise.

The reason for changing non-synthetic oil is it breaks down do to heat and gets contaminated with acids and ash from the residue that gets by the rings during combustion. These contaminates will corrode and etch the machined surfaces in the engine and cause bearing failure and premature wear.


Synthetic oil is a bit different it does not break down. Originally developed for jet engines that produce very high temps and spin at 30,000 rpm's or better, standard oil would not do. Some of the benefits is it really does not break down so in jet engines you dont change the oil unless water gets in it. Automobiles on the other hand still have contaminates from combustion so you have change it. I will point out though, several boat and car racers I know do not change the oil, only change the filter. I dont recommend it but there are people who swear by it. I change my synthetic every 7000 miles, if you change it every 3000 miles or so you are wasting oil. But hey its your money and your right to change your oil as much as you want. There is no major difference in synthetic oil so any brand is OK to use. For me I prefer Castrol but thats just me.
