Wow I don't know why I am struggling here in good old texas. I will just order online. Thanks

Having a difficult time finding the motorcraft Dino 15w-40 diesel oil as well as the 5w-40 synthetic. Even on fords official site. I thought I heard something about rebranding of fluids, can anyone shed some light on this?

I didn't expect it to take too long for that to be quoted. lol

Thanks but that doesn't really tell me what is the best performing oil out for the 6.7.

Well I guess I should have come here first. My old 6.4PSD was amazing on the old formulation of the Delo400LE but then that went bye bye and so did the truck. I traded it in yesterday for a nice new shiny and new car smelling 2019 King Ranch Super Duty with the 6.7 Powerstroke. So where is the...

'08 Optimax 200hp. My issue is this: Mercury Marine recommends Optimax oil or Mercury premium plus as acceptable for use in the new Optimax engines. My local Mercury Marine dealer and Service provider ONLY sell the Mercury Premium Plus Synthetic blend oil and upon asking the question why I...

I have a 1995 Honda Shadow 1100 which I just recently changed the oil with synthetic castrol "V-Twin" motorcycle oil. Now the clutch slips when put under a hard load. Ideas if any on how to correct ? I got home and drained the oil immediately while hot in hopes of getting a good drain. Is there...

I have read numerous pros and cons for Motorcraft 5w-20 (Conoco) oil. I have seen alot of UOA's for Mazdas using this oil and they look very impressive but how about a hard worked modular Ford engine ? I seen a real recent one on a V10 used during summer conditions and trailer towing which is an...

You are the proud owner of a new 2004 Ford Lightning truck. Bear in mind this truck has a 5.4L modular supercharged engine which is conservatively rated at 380HP. You want the absolute best protection for the engine as it is quite an investment and you know it will be occasionally run in the...

OK. To start I know this question has been posed before but from my research it seemed like alot of 2x-20W bashing rather than hard factual data to back a recommendation. I want to hear recommendations for the best oil to be used in a hardworked 5.4L supercharged V8. Factory fill is 5w-20...

Mine is a 2004 which has 8 threads per plug thank goodness. I am going to do the first drain/filter service at 500mi. Then do another 1000 mi with the Ford 5w- 20 but was really wanting a far superior oil to run after those first two "break in" changes. I really want full synthetic just need to...
