True, I change my oil before I put my car away for winter, and when i take it out, it maybe has 50 miles on it MAYBE haha

My oil gets dumped about every 5-6 weeks due to the mileage that goes into the daily commute back and forth from work.

120ish miles per day x 5-6 days a week = 600-720 per week

Sometimes I'll cheat a bit and roll it up to 4k between oil changes, Otherwise I'd be doing an oil change every month.

With all those highway miles 4K is more than safe, you could easily do 5K even with conventional oil and have no issues. Try having an oil anlysis done on a sample after 4K, I bet it will still be mint.

Synthetic oil is more a time oil, not mileage. They say 6-8 months. My truck gets changed 2 times a year.Pretty much every 8-9k miles.

Thanks man, just read up on it a bit more through Mobil 1's website. Up to 15k! That means I could almost go 6 months or so without an oil change lol.

Here's what has been said through Mobil 1's website:

Question:
Recommended Oil Change Intervals for Mobil™ Motor Oils
You state that your oils are for 5,000, 15,000 miles, but what are the months before a change is due?

Answer:
We recommend you follow the oil and filter change frequencies shown in your owner's manual. Generally, this means changing your oil every six months when using Mobil Super™, Mobil Super High Mileage and Mobil Super Synthetic motor oils, and every year when using Mobil 1™ or Mobil 1 Extended Performance synthetic oils.

------------------------------------------------

Question:
If I go longer between oil change intervals, do I need to change my oil filter more frequently? Or do I need a special filter?

Answer:
Continue to change your oil filter when you change your engine oil. Special filters or more frequent oil filter changes are not required;, however, some low quality filters may not be capable of protecting your engine throughout an extended oil change interval.

Mobil 1 Extended Performance Oil Filters provide outstanding protection during longer oil change intervals - up to 15,000 miles of Guaranteed Protection when combined with fully synthetic motor oils. Mobil 1 Extended Performance Oil Filters are designed to remove more impurities (99.9 percent Multi-Pass Efficiency Test rating) and hold more contaminants (22.5 grams capacity) than conventional oil filters, which make them ideal candidates when oil drain intervals are extended. All new car warranties remain in effect when Mobil 1 Extended Performance Oil Filters are used. Follow your vehicle manufacturer's recommended oil change intervals.

Parts stores run specials all the time on Mobil 1, 5 quarts and a filter for like $33. I run it in my daily driver, just went 14,000 miles and had a sample analyzed and it looked fine.

Just got to find a way to trick the oil life monitor dummy light.

I run 0w30 german castrol. When I can't find a good deal on it I run the 0w40 Mobil 1.
