Hi all , my 01 Silverado just hit 400,000 ..she's not so pretty anymore , but runs perfect !! Rolling proof of the longevity of the LS engine !!

 

Congrats!

565,000 miles and it's still going with its third owner, 1988 C1500

 

RIGHT ON OLDBLUE !!! What has your general method been for services? I stick to the suggested service intervals and since around 100,000 I have used one of the products that many refer to as "SNAKEOIL" and I will swear by it. at around 260,000 I switched to 15W40.

 

In the big truck, I changed Dino oil every 3,000 miles, changed transmission fluid every 100,000 miles along with the rear differential lube. I'm a little OCD in that case!
For the HHR, I run synthetic 5w30 Castrol Edge , change it every 7,500 miles, change the transmission fluid and filter every 100,000 miles.
On both I use a K&N air filter, wash it every spring. Keep it clean and drive it often!!

 

Well Oldblue I guess we are the only HIGH MILEAGE HEROES ..LOL

 

I've got a 98 Dodge Ram with 181,000 miles. Bought it new. At my mileage rate, I should hit 400,000 around uhhhh..............the year 2040.
Highest mileage vehicle I've ever owned.

 

Before I got my 2008 HHR in 2013, I had a 1997 Toyota Tercel with 275,000 miles on the clock. I sold it to a friend for $1.00 with full declaration of its problems.

 

In context, I am shamed. I have had 2 cars hit 142K+ miles, but my HHR is now at 141K miles. I hope to break my own record, but 500K+ seems out of reach with an HHR SS.

 

2000 S10 Reg cab stepside 4.3 V6/Auto 203,234 miles on the odo.
next is my Red Wagon 2011 2.4 I-4 135,xxx.

 

You said vehicle right?
