The oil debate is like beating a dead horse! But I do have a story to tell. Years ago I was in a machine shop in Las Vegas getting some work done on a 454. The shop owner was a nice guy and asked me if I wanted to tour his shop. It looked very nice and I obliged. During the tour he started talking about how they were building some engines for John Force at the time and they were having some failures. He stated after exhaustive searching for the problems he called Castrol oil and they told him not to use their oil in John's engine's use only Mobil 1. Their problems went away. I took that to heart. Just a interesting story. Jim.

Since Mobile 1 oil has been brought up. I have a good friend that's job is to figure out why million+$$  motors fail.  He said that Mobile 1 was the only oil company that would stand behind their oil when they showed them that there was a problem with their oil and it was the cause of the engine failure.  Needless to say, after that, they only recommend Mobile 1 oil.

I looked up John Force Racing and none of their sponsors are a oil company besides VP Racing fuels.

Would love to pick the friends brain,and find out more info,just think for a moment,if you have any oil that is causing engines to
fail it would be doing it to every engine it's in,many of these failures are improper use of the oil such as,using the wrong weight,going way past the change interval,only buying the minimum amount for your oil burning engine and then adding dino
oil then blaming the synthetic,another one to think on,any major oil maker where it is actually shown and proved that somehow
their oil caused a problem would have to stand behind it or go broke.

I'd be real interested in seeing a break down of the additive packages on all these oils that we are talking about. Both Dino and Synthetic, that's where the rubber meets the road. How often are you guys that do the extended oil drain change the oil filter?

On the coach with the 8.3 I went 20k miles and that was with the bypass filter that went down to 1 micron and it also added
about 3 qts.On my cars I go once  a year on oil and filter but only put on a few thousand miles.

Coach is once a year. Other vehicles never more than 5K. Oil is cheap especially if you have a 5 liter sump.
