TheDamned said:umm all these craps about synthetic oil is true ?
I've been using Castrol Regular Oil since a while... If all this is true I'll switch... But i heard going from reg to synthetic is bad.. anyway...
yellow1995Cobra said:No problems switching. Ive heard if you have 100k+ miles, you might get an oil leak. I did it on my old engine at about 60k miles, no probs.
Also, if theres a Cosco around your area, you can pick up a case of mobil1 for under 20 dollars. Where as autozone sells it for 35+.
StangJonGT said:Yes, synthetic oil will protect your engine better for longer, and will increase horsepower. The only problems associated with switching to synthetics is chance of oil leak; this only occurs on a very high mileage engine or a beat engine.

yellow1995Cobra said:Yes you will be fine. While your at it, change your rear end gear oil to synthetic, and tranny fluid as well. Should be good for a couple ponies, as well as better protection!

I have interesting links about this exact topic. I recommend RedLine fluids/oils in your diff and tranny.

I have a ford dyno book, that dynoed a stock 5.0 to the tune of 2 peak HP and 4 peak ft/lbs more with just the synthetic swap.. The HP increase was a nice 2-3 throughout the whole rpm band.
