I'm sure that this is a hot topic, but I have a very specific question related to it.
When I first bought my Stang this last summer (it was used), it was running conv. oil. I got that drained ASAP and started using Mobil 1 full synthetic. It has ran fine ever since with no problems.
I know that Royal Purple is very highly regarded among Mustang enthusiasts. I am doing another oil change in a month or so. Is there any significant difference between Mobil 1 and RP? Will my MPG improve? Will my engine life increase? Is there an oil even better than RP that would be significantly better than Mobil 1?
ALSO, I bought a DENSO oil filter and was planning to use it at my next oil change. Has anyone had problems with DENSO oil filters? Is there any noticeable difference between DENSO and RP or K&N oil filters? Finally, is there another oil filter brand that I didn't mention that would be noticeably better than DENSO?
