A friend of mine runs a turbo mod motor in his Fox Body and told me that when he leans on the tune too much it will eat a rod bearing due to the rod bearing having so little surface area to absorb the shock.
He drops the pan, replaces the bearings and backs his tune up.
I always run Motorcraft 5W-20 in my car. I was told by a engineer many years ago that it is a very good oil.

thanks heater! thats the way i look at it. the guys that designed theese things know far more than us ? thats why i went with fords weight. i was gonna use motorcraft but went full synthetic. my tune is 12.0 a/f across the board after 2k rpm. it looks as if he didnt tune below 2k rpm.... and it did have a hicup at 1500 rpm if you brought the rpms up slow
12.0 is too lean for these engines...especially on a dyno that doesn't properly load the engine.
From what I have been told 11.7 is the ideal A/F ratio for these engines.
Also remember that the blower adds additional heat to the engine and when the engine is usually tuned on a dyno, it is tuned at a more cooler temperature than you will usually ever see in the real world.
I hate that you didn't get what you asked for from your tuner. That's why I did a bunch of research before I took mine to have it tuned. The guy that tuned mine spent over 3 hours tuning it and my car is nothing special as it's just your standard bolt on's (including intake swap
).

No....do some research on why 5w20 is recommended from the factory first. I assure you it's not because of your tight bearing clearances lol.

alot of times on a motor with tight clearences it will starve the top half if 15w40 is used. why didnt you design engines and oil if your beter at theese than the engineer? and whats your opinion on the 12.0 af?

I've got mobil in my car now and that's after using 10w30 and 5w30 amsoil. The 5w30 amsoil is quieter than 10w30 mobil...Mobil doesn't seem quite up to par with what it used to be.

You can run pure water for all I care. And run 12.0 on a PD blower car if you want also.

so ****** funny huh? karmas a bitch keep running your mouth. 1. i trust fords oil recomendations over yours anyhow. 2. i told my tuner to be safe. i didnt get what i asked for. 3. that 15w40 didnt keep your poser 99 cobra from blowing up did it?

Atleast mine came with a Cobra motor. Seems yours is more of a poser than mine.
