do it all myself...just like the boat

in fact I just changed the oil today. Delvac 1300 and Wix/NAPA Gold filter. Also changed the Allison spin-on filter ($9 w/tax at the Allison dealer around the corner). At 1200 miles it was time for both. The engine oil was BLACK and THIN cold. Put in my Fumoto drain valve also.

Topped off the rear axle too. It was a qt. under spec (most of them are, or lower ). Funny thing is the rear axle level was the only thing I asked them to check at PDI based on prior experience. I had a qt of "grape juice" here left from servicing the last one so I filled it to spec. It will get a complete change @ 5K or so.

The fuel filters are cake too...

my self the dealors want to munch rat bastered fleetgard filters from cummins alantic . the dealor charges $45 for a $ 12 for a fg fuel filter $37 for air 13 at ca and $12 oil 8 at ca they will neaver touch my truck .

oh i would hate to see what they charge for 3 gal of shell rotella t .

Alot less than a motor.

I've had 3 engines go over 400K on Mobil 1 and still going without any repairs whatsoever. Running strong when the chassis gave out. Synthetic is a sucker bet.


You GM guys are spoiled with your cheap oil changes- the 6.0Ford filter is $50
