When you go to your dealer for an oil change, note what they put in. If it is from a quart container, read the weight. If it is from their bulk supply, ask what weight it is. If they say 5W20, ask to see the tote. If any of you discover that Ford is putting 5W30 into your vehicles, I ask to be informed by email and this forum ASAP. Please also include the location of service if this occurs. Thank you

Got my gratis 1st oil change at the dealer's quick oil change bay last week. The two grease monkeys weren't very busy, so I was able to chat with them and make sure they put the right stuff in. "We wouldn't do that to you" was their reply. Must have been their first Bullitt change. They were bugged-eyed and talking up the car. Too bad the service department wasn't as enthused. More on that later this week when I conclude my headlight/gearshift knob replacement saga.

So are you supposed to put 5W30 in it?

Wade,
NO. Your spec calls for 5W20. I have written and sent Ford technical data for Schaeffers 5W30 with a request to use it under warranty. The reasons being is that Schaeffers 100% parrafin, semi-synthetic and pure synthetic base stocks are superior to the "hydrocracked base stock from Ford's supplier. There is only one producer of this particular oil in N.America and because it is such a niche market right now ( new Fords and some Hondas use it), specialty manufacturers like Schaeffer see no reason to produce it. It's a supply and demand issue. The 5W20 makes me nervous because it is considered a "break-in oil". I am changing out my oil every 1500 mi. because I am not confident that it supplies the additive package to protect my engine. If I receive the go ahead from Ford, and can use Schaeffers, I will be confident with 7500-10,000 mi. oil drains.

So should we get the oil changed at 1500 if there going to put 5W20 in it?

I changed my oil at 600 miles and put in 5.5 quarts of Penzoil 5W30 and a K&N oil filter (I could not find a Mobil 1 oil filter).

I do not like the 5W20; I think it is too thin at the high temperature. I also think that 5 quarts is too little for these motors. If anyone with a Bullitt autocrosses (i.e. pulling g's), I would run 6 quarts.

My 1996 Mustang GT had a 6 quart oil fill. I donot remember the year that GT changed to a 5 quart oil fill.

Bullitt, GT, and Cobra all use exactly the same oil pan. Cobra has a 6 quart fill plus an oil cooler. Bullitt & GT have a 5 quart fill with no oil cooler. If you put in more than 5 quarts the next time you change your oil, just scribe your dipstick so you can keep it up.

MY OTHER SUGGESTION: DO NOT LET YOUR BULLITT OR GT RUN LOW ON OIL. CHECK YOUR OIL EVERYTIME BEFORE YOU DRIVE. DURING BREAK-IN, OIL CONSUMPTION CAN VARY; SO KEEP IT UP ON THE STICK AND YOU WILL HAVE A HAPPY LONG LIFE MOTOR!!!
