Oil & Filter

Oil & Filter
I run 7 quarts of mobil 1 synthetic 5w-20 on my cobra and a motorcraft filter. Several ford mechanics suggested this set-up because cobra motors are known for spun rod bearings due to lack of proper oil pressure. Discuss your oild and filter!

Hmmm. I dont own a Cobra, but Ive never read or heard about this. Im also not very fond of dealerships and their mechanics. So IMO, I wouldnt listen to them. As far as I know, its bad to run too much or too little oil compared to the dipstick. Do more research on modulardepot.com, modularpowerhouse.com and svtperformance.com.

Too much oil can certainly cause bearing failure, especially on the camshaft journals. Windage can cause your oil to "froth" up and get foamy when there is too much oil in the pan. As a result, low oil pressure causes starvation. At most, fill your pan to the top hatch marks on the dipstick while the motor is cold.
EDIT: IMHO, I'd also reconsider using the factory recommended 5W-30...Mod motors have very tight clearances, and the lower weight oil is thicker which is exactly opposite of what you would need on a motor with such tight spaces. Again, search around the respected boards and see what you can come up with. You'll get lots of opinions!

Ack.. I just noticed I have the weight statement backwards The lower the numerical value, the thinner the oil is. Yes, mod motors need thinner oil.

I used to run mobile 1 5w30 untill i switched to amsoil 5w20. I didnt have any problems running mobile 1 even during hard runs like at a road course or the local 1/4 strip.

Im sure its .01 mile per gallon but on paper thats millions of miles with all their cars. I think they got a government grant out of that as well.

I've heard Amsoil is great stuff. I can't find it anywhere local, but when I finally get my motor issues straightened out I think I'll order some. How often do you change your Amsoil?

Mobil 1 does offer a 5w20 thats what i used for my last oil change..

I usually use either amsoil, redline or castrol GTX. I change my oil and filter every 3k. My oil choice depends on what I'll be doing that season, if it's just to work and back then I'll use castrol, if there's any kind of performance driving to be done then I pony up for a fresh shot of synthetic.
I have an 8 quart system with my oil cooler in place so I never really have to worry about having enough oil. I'll use any filter as long as it's not Fram or another allied signal made unit. Warner, WIX, and motorcraft are all the same filter and I use those almost without exception. Usually I'll go to my local Oil Changers store (like goofy lube but not so full of morons that leave filters off and drain plugs out) and buy one of their Warners. I used to manage some of their stores so I still get a hookup on the price.

I have used jiffy lube before and I will never do it again. The guy there kept telling me that I needed a new air filter cuz my k&N was a little dirty. I was like "No, my filter is fine." Then the guy went on to explain how the engine breathes and all this other BS that I already know. After getting him off this subject he said that I needed a new brake light. So I told him to show me the broken brake light. After he gets in the car and I step behind the vehicle I see both brake lights are working just peachy. So I complained to there manager and got that oil change for free. GO ME! Redn3ck do you know where to get a good tranny/oil cooler?
