Then I need to change oil to Mobil 1 high mileage 5w30 and WIX filter.

Probably check transfer case and differentials, swap out Mud/snow BFG Long Trail for the Mastercraft Courser ATX's for winter

[hawgrider]

Don't those things have quite a few fuel pump failures?

[BucketBack]

That was the S10 Blazer. The Trailblazer is the replacement though

[hawgrider]

Yes the Blazer.

Guy at work had one 2 fuel pumps a year.

Then I need to change oil to Mobil 1 high mileage 5w30 and WIX filter.

I'm sure you're aware, 7 quarts.

[BucketBack]

Somebody wrote 7 quarts with filter in paint under the hood.


I have 15 quarts of Mobil 1. It was on sale at Meijer for $23, and a $12 rebate , max $24 rebate

What year is yours?.we are possibly looking for a trailblazer or envoy.or a 1/2 ton crew cab P/U 1/2 ton.

I am a born Ford guy but a full size Ford has that stinkin triton junk,overhead cam,spark plugs a mile down in engine.nuthin like a pushrod engine.

The 4.2-liter Atlas LL8, otherwise called the Vortec 4200, was a groundbreaking engine for GM. It featured an all-aluminum construction, dual overhead cams with variable valve timing on the exhaust side, four valves per cylinder, a coil-on-plug ignition system, a high compression ratio of 10:1, and its cylinder heads featured GM’s then-prevalent “Vortec” engineering designed to maximize airflow.

EWWWWW, dual overhead cam.I may just look for a F/S chev/gmc 1500,5.3 LS motor.

2006, with under 90K miles

[MI.oldguy]

Decent mileage?.

[BucketBack]

Not what they say anyway. It runs good in the snow and sand
