I know others,including my sons Ranger with over 300,000 miles with higher than 10,000 mile OCIs, 15+, on reg. M1 and doing fine. Most of the reg M1 noise is BITOG stuff. StevieC, I'm not critizing you at all, but there is a perseption on BITOG that doesn't always back up real world experience.
Tig I understand what you are saying... I too would have no quibbles about using the new regular stuff for as long as you described, the point was that people need to know that the regulars stuff from a few years ago is still available, but under a new name.
Either product is excellent, but if you are as anal as I am you want the best, and IMO the "EP" is the best regardless if you use it for extended OCI's or not because it's additive package is very stout compared to the weaker version which is now "regular".
Sure your Taurus example will show that it is possible to go 10K miles with the new regular stuff, but that is an "easy on oil" engine that is virtually indestructible anyways.
Give me a sludger engine and show me 10K on the new regular stuff, that will make me a believer. Because the EP stuff will hold up in these engines for that long. I have seen it!
