Do a Google search for Range device for your make and model and should pull right up.

did u mean you change the oil every 3000-5000 miles?

You betcha. $35 is way cheaper than the alternative. My wife drives like fuel is free and I still come out ahead after 90k miles. If you lover, lube er.......

@ls200608. If you want a RANGE and can't ship it, PM me and we can work it out. I'm all about stuffing BS emissions up the ignorant govts ass....

I have a 2019 GMC Yukon with 6.2L and 10 speed. Got a Range device and it does work on my car. Actually my around town mileage improved a little. Now about 15.9 mpg.

Installed a tune 25k miles ago & turned off the AFM on my 2018 Yukon Denail 6.2L 10 speed. My mileage is 20.2mpg & my best tank ~500 miles was 26.9 mpg.

What was it before, with AFM?

Hey guys, new to the site. My 2019 Tahoe Z71 just had a collapsed lifter at 47000 miles and I'm quite shocked that such catastrophic engine failure can occur at such low mileage.

The truck was well maintained and ran butter smooth before this incident and there was never any sign of problem until this happened yesterday. Thankfully that I was very close to my dealership (Dublin Buick GMC in Dublin CA) at the time and limped to the shop, the service advisor told me to wait a day before it can be diagnosed since they are having a labor shortage and parts shortage. Got a call today from him and was told one of the lifters from the passenger side bank had collapsed and they have new lifters available but not the VLOM, which is in national back order. Since the engine is not taken apart yet they don't know if there's further damage to the cam or if the pushrod is bent. According to the advisor they can only replace all the lifters of the affected bank but not the other side. Apparently I'll be driving my rental for no less than a month or maybe even longer.

I'm just wondering what are the odds that after this repair one or more lifters from the driver side bank fails without any warning ?! I have always been told the weak link in these trucks are the transmissions which prone to torque converter failures around 100k, never would have imagined engine can fail at just 47k.

I have yet to see the driver side lifters fail on the k2xx 2015-2020.
