Well I did some reading quite a bit actually I was off work and had plenty of time. I have decided to stick to conventional at 5,000 miles in the 2014 focus. My reasons are this being a di motor and their lack luster repore in general it makes me feel more comfortable. Also being a mechanic I see a fair amount of engines. The ones that are going longer than 5000 miles generally aren't as clean. Don't flame me please it has just been what I have noticed. I read keeping the oil clean is one of the best things you can do to help di carbon build up. Also I'm running pp in the focus and the oil is at about 5000 miles and it's noticeably darker than my mom's 09 focus with 80,000miles while doing 7500oci on it. Which makes me think the di 2.0 is harder on oil than the old 2.0. So maybe I am wrong abut all of this but I'd rather play it safe than have an issue down the road with carbon build up on valves ect. I plan on doing oci on the pt every 6 months which is probably about 4 to 5000 miles but it's mostly short tripped and dodge ram gets it every 6 months to. So in the focus which would be a good oil to use? I'd like to stick with something and not change based on a sale. I am considering Mobil super vwb as my tops but any opinion or recommendarion is appreciated .
