Synthetic oil
#16
Change mine in both my crown Vic and F-350 V-10 every 3000 miles at the selling Ford dealership. His charges aren't out of line around here.
A breakdown of his "fast lube" program is:
- 6 qts of Motorcraft 5W20 QSP oil
-Motorcraft FL820 Oil filter
-Inspect transmission, PS, MC, WW, Rad.
-check air pressure in all tires
-inspect exhaust, chassis, susp, engine cpmpartment.
-Lube chassis where applicable
Total charge------$28.69

Based on used oil analysis I'm running a 10K mi oil change interval. I could easily go further, but 10K is a nice round number. I'm using M1 syn, 5w30in my gas engines and Rotella 5w40 inthe diesels. Great test results, no wear metals and plenty on oil life left at 10K. Spend the $10 and see what your oi looks like at your current OCI, I'm betting you're changing your oil way too soon. For 25 years I was a dino, 3K mi OCI guy, religiously. What a waste of time and resources, switching to syn and an extended oci made lots of sense for me. We put 50K mi's on the cars/year and another 200 hours/yr on the diesels.

John2Thomas you are right on the money.
Heres a list of the cars & trucks that i've owned & used Amsoil synthetic engine oil in since 1979.
My 1968 F-100
My 1980 Corolla
My 1987 Ranger
wifes 1984 Corolla
wifes 95 Taurus
Based on used oil analysis I changed the oil in all of these every 12,000 miles.
The F-100 was bought used & I put a rebuit engine in it. Drove it 120,000 miles & when I sold it the engine was still in EXCELLENT condition.
Bought the 1980 Corolla new, drove it 165,000 miles & when I sold it the engine was still in EXCELLENT condition.
Bought my 87 Ranger new & i'm still driving it. The engine has 230,000 miles on it and is still in EXCELLENT condition.
Bought the 1984 Corolla new & sold it with 180,000 miles & the engine was still in EXCELLENT condition.
Bought the 1995 Taurus new & wife is still driving it. It has 195,000 miles on it & the engine is still in EXCELLENT condition.
It makes my blood boil to be paying better than 3 dollars a gallon for gas AND to STILL hear the quicky lube commercials telling me to change oil every 3,000 miles.
Such a waste of the crude oil that we have to pay to import.

Don't get too fired up, as old motor oil isn't wasted, it is all recycled into winter heating oil in shop waste oil furnaces and other uses.
And oil never loses it's lubricating properties unless it is overheated and burned. The reason for regular oil changes is contamination that can cause premature bearing failure. This contamination can occur with high dollar synthetic oil as well as the plain old Motorcraft 5w20 which isn't cheap either. If you are running in a dirty environment such as on gravel roads, then you have good reason to change frequently. If you are primarily in city environments with paved streets, then you might get by with something other, unless you are having problems with something else leaking fluids into your crankcase or overheating.
