I run Amsoil,& use Napa Racing Filter's we do change it quiet frequently..so far so good.and after 2 season's of running hard & proper maintance.. i suppose any syn..oil will do. i run 2 10.71 littlefield blower's. not to say the engine's haven't let go. They have. but not from the oil.

How many here have ever had a engine failure related to oil composition or breakdown? Just curious.

True that synthetics can agitate an already leaking engine but they do work better. I like Mobil 1 myself. It is the only oil that would keep my turbo bearing clean. Another interesting thing I learned. I tried Pro-Long engine treatment in my turbo car and noticed how much cleaner my oil return line was. I never was one for oil additives but I was pleasantly surprised by Pro-Long.

i have ran two trucks to over 300k with valvoline conventional oil with no problems so I just cant justify the extra expense but i do change my oil overy 3k miles and twice a summer on the boat.

Mobil 1 all the way.
Even the mower runs on it.

I'ved used it in my old Bronco II for 100K+ miles, the wifes old Dodge Daytona Shelby Turbo for 110K+ miles, my current truck for 70K and the wifes new Mustang for 13K.
No trouble what so ever.
I even used Mobil Synthetic ATF in my truck when I changed the fluid last time. That was expensive. Fourteen quarts cost me 45-50 bucks.

Most everything I've seen on this subject revolves around how often you normally change your oil. Consensus of everything is if you change it on time conventional is just a good. If you're prone to going long on changes, then synthetic helps because it takes longer to break down. Other than that it's the "feel good factor".
Personally I use a blend in the engine (compromise okay?) and full-synthetic in the drive "only" because of it's tolerance to heat exceeds conventional drive oil before breakdown....If you want to feel good, spend away...

We have never used synthetic in anything. Our fleet of vehicals run on quakerstate. The boat motors run valoline VR1. I like good old thick oil.

A interesting fact I read. Last few motors I have run GM camshafts, in which are crane cams. In the instructions they have a huge warning telling the installer not to run synthetic with the roller cams They say if there is not enough spring pressure the roller could actually slip on the cam lobe and create a flat spot, all because the synthetic is so slippery. It sorta baffled my mind.
