[QUOTE="bubblehead93, post: 10027227, member: 96609"] Don't know about the have to versus should versus don't need to about synthetic oil. I've dabbled on cars for about 20 years now (had to pull my shoes off to count that high, jeez) from SBF to FE to 2V and 4V. Started off with conventional oils, progressed to the blends, and now have used full synthetics for about 14 years now. Pulled the motor apart in my 97 ford f-150 to re-cam and time it. It had seen only synthetic (10w40) since the first oil change at 3000 miles. It was at 125,000 miles and had no ridge at the top of the bore and you could see plain as day the factory cross-hatching in all of the bores. I have never seen that from any conventional oil or blend. As far as the 5w50 vs 5w20 in our motors. I was not aware of the GT500s running 5w50. my experience with racing FE motors usual resulted in 5w50 being a necessity for decent oil pressure due to the large clearances (relatively speaking) we would run in the mains for higher rpms. Would be curious as to the main bearing clearances on the GT500 relative to the Cobra. danger in a motor with factory clearances is you push too much oil pressure and the oil pump relief bypasses oil, so in effect you have more pressure but less oil flow. might not see any ill effects on a street driven machine but I would be wary on a motor that is raced without first doing some more homework. also, these motors tend to collect oil up in the heads, would be nervous that the heavier oil would exascerbate this effect by slowing drainback (had the valve cover off a 2V once while running to diagnose a valvetrain noise, quickly modded an old valve cover by cutting out the top so i had access while minimizing the spray - never saw anything like that with old pushrod motors lol).
