motor oil.




















one generally wants to run the lowest weight that maintains pressure at all times. any quality synthetic (i prefer PAO or PAE basestock) will do fine.

good luck.

Go with semi-senthetic if you have to. Use 20-50 in hot weather and 10-40 in cold weather.

I use 5w/30 blend motorcraft. With synthetics its true that it will stick to engine parts so you wont have such a hard "cold startup" however your oil needs to be able to travel through many different small areas throughout your engine and a pure synthetic is extremely thick and hard to get through those smallers areas so you are in essence starving your engine parts of much needed oil when it is under the most load ie when you are driving it.

say what? a synthetic will outflow a conventional oil, not the other way around. the synthetic nature of a G-III, PAE, PAO [et al] basestock allows them to have a lower pour point while still meeting SAE requirements (read that they flow better, not worse, than dino oil).

10-30 and keep it clean...that's what's best..oil tech is quite good these days be it synthetic or conventional...I ran 10-30 MAX LIFE from valvoline and consumed less oil and found less loss due to leak on my old 197,000 motor.

I have and will only run Vavoline oils in my vehicles (This Mustang being my 2nd fox) and I have never had a problem with leaks in any of the Mustangs. If your car has higher milage on it, the fossil oil will not leak out because it is slightly thicker than a synthetic oil.

My .02 is that no matter what you choose for oil, you need to stick to that choice for the entire life of that motor. Some people may not agree but that is OK.

Amsoil all the way, Mobile 1 is way better than Royal purple. search the web and look at test results. and also Amsoil is 100% synthetic others like royal, mobile, red line and synthetic base but are not 100% synthetic.

go to amsoil website
