This is inspiring but I still feel like synthetic is better not because it'll last longer, but because it runs cleaner. I could be wrong because I actually never used to use synthetic until I got my Blazer, which I'm trying to baby as much as I can. Wasting money on it isn't a huge issue to me even though I, too, religiously manage my oil, and usually change it at around 4,000, despite synthetic supposedly being good until around 6,000.

 

i got 352,000 when i blow the head gasket, new motor last month, total on truck 356,400
great truck LIKE A ROCK

 

If your changing it every 3k, then yes - synthetics are a waste. I go 25k or one year on Amsoil Signature Series in my '07 Silverado. I don't go easy on my stuff either. If you do alot of highway driving and put that kind of mileage on every year, synthetic is actually cheaper - 1 oil change, 1 filter vs. 8, and 8 filters.

Since I'm here, the '00 Vortec I threw in our '89 S10 I estimate to have around 155k miles on it now. Had about 146k when I did the swap.

 

just hit 130k today, and I've had the 1-2 transmission shift problem for 25,000 miles now...trans is still good tho haha, and it only does it when i get off the freeway.

 

Retired a 96 with 256K only due to rear frame rust,did the [email protected] 220K,sold the unit for parts over 2 years ago and heard recently it was transplanted to another second series Blazer and is still running after an additional 45-50K put on it-amazing!

 

2000 with 197k w/ original 4.3 motor & tran... only typical maintenance done.

 

2000 with 175,000 miles. Second transmission, second transfer case, third transfer case motor...2nd fuel pump, working on a third...2nd rear axle..hmmm...sooner or later, intake gasket...at least 18 door pins....3rd transfer case switch...the spare tire sits in the back as the tire mount died a long time ago....thank goodness I married a mechanic or the dirty girl would have been sold 3 years ago when the transfer case took a poop. Looking for a diesel station wagon to replace the dirty girl.
