No, of course! I genuinely appreciate the insight. A lot of this was done from memory and in the middle of one of my more boring classes, so there are sure to be things I miss.

 

So dumb oil question here.

I was looking for Rotella at Pep Boys today, and they only had the 15w40 in the silver jug and the 5w40 in a blue jug.. T5 is semi synth and T6 is full synth, but its ok to mix the 2?

I'm in Denver and we are having a fairly mild winter so based upon the recs for oil, the blend of the oils mentioned above is what i should be doing?

 

Odd they only have it in the silver jug. I get the white jug of dino (traditional non synth).

Check Walmart though if you have one close. They always have the best oil and coolant prices.

If the silver jug of 15w40 is all you can find, then do still mix that with the blue 5w40.

 

Alex_M, for automatic transmission anything wrong with using Dextron VI, instead of +4? The local parts store near me has Dextron 6 in stock and I don't want to wait to order the +4.

Thanks

 

I've been doing some googling around about the compatibility because frankly I wasn't sure. I didn't see anywhere that outright said "no, don't mix the two", but most people seemed biased against it.

Odd that you couldn't find ATF +4 though. My local Advance Auto and O'Reilley have it. Advance had it in a house brand (Carquest I think); not sure about O'Reilley.

 

I've been adding dex 6 for the last couple years. No issues. I change my fluid every year. 221,000 miles

 

Lol I don't know what they were smoking, I walked into the store last night and saw ATF +4 everywhere... It's all good now

 

I wanted to add my "Do List" that I compiled which gets done ASAP along with the 60k service.

1. Buy an Ultra-gauge
2. Do the In-Line thermo mod
3. Flush the coolant (go to green)
4. Replace the 3 tensioner pulley bearings
5. Replace cap on coolant overflow tank
6. Bypass throttle body heater
7. Replace battery (go to interstate)
8. Replace battery cable ends
9. Do the In-line PCV mod (recent post about this was good)
10. Have a spare key made
11. Do the upgrade for the wiper arms and blades from Lucky 8
12. Pull off those ridiculous running boards if it has them.
13. Pull out those rattling jump seats.
14. Get a few spare clips for the fuel door.
15. Blow out sunroof drains
16. Clean out the blower squirrel cage.
17. Replace gators on Pbrake and trans case levers
18. Fix the headliner if needed.
19. Install steering wheel cover
20. Replace the 2 rubber boots on the ends of the windshield cowl
21. Get a cheap little set of tools that come in those plastic boxes for each vehicle.

 

Add, #22 oil pressure tap monitor?

 

I would think the Ultragauge would be an already must have purchase, not a 60k item
