Sierra Sik

mobil 1 annual protection 5w-30w, changed per OLM which is every 7,500mi. Fram Ultra synthetic filter. 92,000mi. on 4.3 v6.

https://pqia.org/shell-rotella-gas-truck-full-synthetic-sae-5w-20-motor-oil/ This is the pqia test results for rotella gas truck 5w-20w. I like the low noack volatility of 7.2 ! Assuming the 5w-30w is similar I think it is excellent oil for the 4.3 ecotec3. Healthy doses of zinc, moly and boron too.Whats to not like?

I previously attempted to have my vacuum pump updated on my 2014 sierra after experiencing loss off braking power at very low rpm while parking. Problem was truck was at 73,400 mi. warranty was only up to 72,000 mi. Dealer said call GMC. GMC said (after 3 calls and 2 escalations) no exceptions ! I was Pissed !! Was going to install pump myself but had not got around to it yet. Than new letter came out with 10 year 150,000 mi warranty. Took my truck in today and dealer replaced pump and performed recall all under warranty. Brakes work really nice at idle and low rpm now. GM should have fixed it on my first request! Oh well its fixed.

how about a few tanks or more of e-85 ? If your truck is capable.

The "Gas Buddy" app is pretty good at locating E-85 stations.

FYI. Today I had 275/60-20 Kumho Crugen's (poor man's Michlen Ltx's) installed on my stock 20" GMC rims. The fit is good with plenty of room with wheels straight. With wheels fully turned in both directions there is no rubbing on the inner plastic/fiber wheel wells.It does come close,Approx. 3/8", but does not touch. My truck is a bone stock DBL cab 2 wheel drive. Z60. I went with the 275/60-20 for a little more side wall on a truck tire. (I'm old school). Do note the 2019 GMC Sierra SLT's use the same 275/60-20 on there 20" rims. I do notice a little less harshness on the road bumps and im at 40 psi .I'm happy with the up size. Hope this info helps.

Have been waiting a long time for this fix.

What about a couple tanks of E85 every once in a while ?

http://www.amazon.com/gp/product/B00XZ9PDXW?psc=1&redirect=true&ref_=od_aui_detailpages00 I found these key blanks on Amazon. Ordered one, recieved it in a couple days. Took it to an Ace Hardware store with proper cutting machine and had them cut the key.Self programed as per tbarn.(insert original key,turn ignition on but dont start vehicle.Take original key out and insert copy.Turn ignition on but dont start vehicle.Dash will show 3 keys programed.) Works Fine. Total cost.$15.00 . $10.00 for key blank,$5.00 to have cut. Note: I did have to take the key back in to store to have depth of cut increased.Guy said that is normal with these type keys.

Sounds like used mirrors and aftermarket switch is only feasible way to go.I m just not crazy about Rube Goldberg rigging on a new truck ?

The service guy I talked to said it is possible for my truck but would be unrealistic due to cost.Kind of a lame answer if you ask me.I have an sle with power adjust and heated. Has anyone done the swap successfully.I dont care about puddle light.Can live with or without signal.Really want power fold for getting in and out of small garage. Any advice ? thanks in advance,Tony
