What kind oil do u use???

Searching the internet and working at a parts store, I've come up with some solid theories about certain things. One, no oil is really a bad oil as long as you keep it changed. I run Wal-Mart Super Tech ($0.89 a quart) in my Ranger, 130K and still runnin. Quacker State and Penn-soil seem to be the most venerable when it comes to sludging. Run a thicker oil in the summer, and thinner in the winter. Dark oil after a change is actually good, cuz it means that it is doing it's job of ridding of contaminents in the crankcase. Also, I've opened up new Fram filters, and you might as well just shove a paper towel in there, cuz that's what it looks like. They also have no bypass, so if it gets clogged, unless you constantly watch your oil gauge, your probably going to burn up your motor. People swear by these filters just because of all the marketing they do, "Before you slam it, Fram it." My favorite oil is Valvoline and Kendall, never seem to hear much bad about either of these. Mobil-1 seems to be the way to go for synthetic, although I wouldn't be afraid of Red Line, Amsoil, or Royal Purple, as I think these are all good products.
 
I started putting Mobil 1 in my 95 Buick Century that my parents gave me at about 130,000 miles. It supposedly had an oil leak(not sure where from) but it was a minor leak. I see no signs of a leak. I would use mobil 5w-30 or Amsoil 5w-30.

Shane, I can see a future project for you - Monster Miata style. :D

I thought about it actually. Took a ride in one of those things. Couldn't believe it. 347 turbo Miata. Nuts. No traction whatsoever. I just couldn't see spending all that money for such a tiny car. Maybe someday when I get bored with the Cobra. I doubt that will happen. My want list keeps getting longer, and my budget smaller.

5w20 penzoil. To keep my oil pressure up. Car has a ton of miles on it
LMAO... That will make your oil pressure drop like none other man. 5W20 is a speciality blend for new Ford Modular motors and Hondas. You should run a minimum of 5W30 in your Stang, and seeing you are also in Florida, you should be running atleast 10W40 or 20W50 in the summer time.
 
guyfox - where are you located? If you're facing a warm summer, you should consider going the other way with viscosity - especially the second number. The thinner the oil, the lower the pressure. The smaller the second number, the thinner the oil will be at high temp. I'd try, as stang8urimport suggests, 10w40 or 20w50 if you're seeing any kind of temps during the summer.

If like many you don't put many miles on the car and simply change the synthetic once a year - I'd put 5w40 in it for year round use.

I live in GA. Gets pretty hot here in the summer. But I don't drive the car that often. Maybe 3 or 4 times a month. Travis at Mustang Services recommended the 5W-30. I have 10W-30 in there now. However, won't be changing it until the Fall. Does Mobil 1 make a 5W-40? Maybe that would be a good compromise?
 
I run 20w-50 all summer in the mustang. I run 10w-40 in the Jeep (winter beater).

Ah, on another note, I took my 5 gallon used oil can to the oil change place to get rid of it, and it was on a -10F or so winter day. The oil that was in there was mostly from the Mustang oil changes (20w-50). It took about 10 minutes to get out of there. After seeing that, I will NEVER start my Mustang over the winter if the temp is below zero and it still has 20w-50 in the pan. Seriously, it did not even look like oil, it looked like really thick chocolate or something. It even makes me wonder about running 10w-40 in the winter beaters when I crank it up in the morning on those -30F days MN gets 2 weeks out of the year.
