No doubt if Fifty150 is involved, it's going to be a long thread!! Many of his replies are more than a foot tall on my computer screen and only a few of them fit on a page which would otherwise hold 15 or 20 replies!
I've read several 'experts' who explain that when it comes to fully synthetic oils, the top 8 are all basically the same. I used to use Mobil One, but then Exxon bought them out and I'm proud to say that since the Exxon Valdez oil spill (and their effort to hire more lawyers to get out of cleaning up the mess they created than workers to actually do the cleaning) Exxon has not got one dime of my money for the last 25+ years - I would push my van down the street if I ran out of gas in front of an Exxon station. They put a lot of Alaskan fishermen completely out of business and then worked the courts so they didn't have to recompensate most of them anything. You've gotta look really hard to find a less eco friendly company anywhere in the world than Exxon . . . . and now their former CEO is about to become our Secretary of State. BP on the other hand, went about it all very differently with their major spill
So, since there's no more Mobil One going in any of my vehicles, I'm using Castrol Edge Extended Performance for the TC which they say is good for 15,000 miles . . . . but Ford says 10,000 so that's what I'll be doing. I have always changed my own oil, but it's not my favorite pastime now at my advancing age so I had really, really been looking forward to just taking it to my Ford dealership and letting them do everything, but alas, both dealers within easy commuting distance of my home have already proved to me beyond any reasonable doubt that I cannot trust them to do the right thing, so my old ramps will be getting used for this vehicle too. With 10K or 1 year changes, it won't be all that often, so I think I can manage for a few more years. At least I'll know for sure what goes into my engine and that the work was done right
You lucky guys who have a reasonably competent dealer nearby don't realize just how lucky actually you are!
