How many miles per year on average? % City vs Highway?
As far as oil loss, how much is lost between oil changes?
Are you driving the steep grades of the Cascades or just around town?
Like I said, Mobil 1 (various grades available these days) may be fine or it may actually be overkill for your needs so I won't blindly just recommend it since it ain't exactly free. <img src="/forums/images/graemlins/wink.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" />
city and highway
I only put about 8K on the monty in the last 14 months. I usually dont take it into the Cascades although i do have one trip planned this summer that will. Honestly this smoke after idleing is so new I havent really kept track how much ive been putting into it (im going to start though)
Walmart seems to have a good price on Mobil 1 High Mileage 10W-30 Full Synthetic for 26.48 (5 qt)
Based on my understanding (others please correct me as needed because I know I'm def not an expert on this) the main benefit with synthetics is they don't break down as quickly.
Certain types of driving activities like heavy acceleration, constantly carrying a heavy load, driving up hill a lot, driving in stop and go traffic all accelerate oil break down.
Do you spend more time driving in stop/go traffic or cruising at highway speeds?
As it is, you don't drive as per year much as most drivers.
Not knowing anything further, I'd be inclined to think you'd get as much wear with synthetic as non-synthetic and you should only be changing your oil 2x per year since these engine's aren't exactly harsh on oil unlike a turbo motor or one constantly used for hauling a heavier than normal load.
