I have a Ford 2014 Sunseeker and I was wondering how many of you use a synthetic oil. I would like to start out with my first oil change using a synthetic. Thanks for all the good advice.
I use Mobil 1 EP (Extended Performance) in our Class C's V10 engine. I switched from standard Mobil 1 to Mobil 1 EP some time ago.
I also use Mobil 1 EP in both of our motorhome's generators. Along with Mobil 1 EP, I also use special spark plugs in both generators. The generators run quieter, smoother, and probably more efficiently ... using both the synthetic oil and different spark plugs.
