Im thinking of doing a full fluid change on my truck. My truck is 09 silverado with 30 000kms on it. I drive it hard and it has to deal with some really cold ttemps seeing as it sits outside, because of this I'm thinking of running royal purple synthetics. Im thinking of changing my front/rear diffs, transfer case and tranny fluid to this royal purple. Has anyone used there tranny fluid? What weight of gear oil do you run in your diffs?

It isn't a bad oil. As for gear oil I run 75w-90 in front and rear diff's.

 

Just curious, how often do you change your oil and service your transmission/transfer case?

I run amsoil in my engine and do oil changes every 10 000 kms. I haven't touched my tranny or transfer case yet. That's kind of why I want to spend some money and get it done properly.

Why not just change out the transmission and T case to AMSOIL or is it easier to find Royal Purple?

I'd go ahead and use Amsoil since you seem to like the product so far.

      Tire psi

      By jgaudet99 · Posted

      Thank you, I'll check that Autel scanner out and see if it will work for me! Ya I can see GM's point of view if they lower the psi set value for someone and the person sell's the truck and the new owner puts the factory tires back on then their could be liability issues cause the psi warning light wasn't coming on when the tires were under inflated for towing their load and then it might be able to be traced back to GM lowering it.

      Tire psi

      I had a similar but different response when I talked to the service manager where I bought my truck in that he said GM corporate won't allow them to lower the placard pressure setting as they would get their hand slapped but that of course they have the ability to make that change. His suggestion was simply go to a tire dealer or third party shop that is willing to reset the pressures lower. However I chose to buy a tpms tool and partly based off of this very forum as it had been proven to work on the 2024 model ( Global B system ) and while I could have paid lots for a full two way diag tool, I didn't want to spend that much and bought the recommended Autel TS 508 and it will reprogram the 2025 model and assume it should do the 2026 as well. However the tool is rather proprietary to reprogramming Autel tpms sensors so that is a function I will never use, where as a real two way scanner would have many uses but also have yearly subscriptions etc where this 508 is free updates for as long as they put updates out for the unit. In any event it worked to lower the placard pressures and I often use it to adjust my actual tire pressures although will check with a mechanical gauge as well sometimes just to make sure that tires tpms sensor isn't lying to me.    My suggestion is either buy a tool that you know will work to adjust the system or start out by getting the tire shop you bought your tires from to reset your truck and if after that you still want a unit to do it yourself, get one at that point.

      Here is an image of a quick Google search about these tires on my truck and it's exactly same psi recommendation the Toyo tires company gave me!    I'm not looking for anyone else recommended psi or anything, I'm just looking to see if anyone knew a way to get rid of the factory low psi warning light, because I'm not running high psi and ruining my tires when I'm not towing!

      Open the driver's door jamb.  What do the cold tire PSI ratings on the tire placard show?   I'm not saying to run it to those numbers, but I would like to know what it says.
