I was thinking about trying 5w-20 in my truck just to see what would happen (lower mileage, less noise, etc), but if the thinner oil doesn't work, I don't want to just dump it out and waste it. I would like to just add something to make it thicker: Back to something near a 30 weight. I would like something that is actually a lube, and not just a thickener. I don't want to use Lucas. Maybe something from LubroMoly. It should also cost less than $6 since that is what an oil change would cost me.
Is there a good/useful oil thickener?

Loobed why not just keep the 5W-20 for the full OCI? Most of the oils you have used of the 5w30 variety sheared into the 5W-20 range and your engine is just fine or better yet just keep using 5w30.

I have not tried it yet. It was just a thought in case I didn't like the 5w-20. I like to figure out all the possibilities before I do something so there isn't any last minute surprises. I may change my mind later and not even run the 5w-20.

2 bottles of STP oil treatment about 5 or 6 bucks at walmart
Just fill it up so it's a 1/4 to 1/2 up the dipstick. If you want to go thicker for any reason, add 1/2 to 3/4 qt. 20w-50.

I vote for this suggestion.
If you're happy with the 5w-20 as-is, you can always top it up with more 5w-20 after the preview time.

That would probably work. I have a 6 quart sump, and it should run with only 5 quarts.

Back in the day, I use to put STP in very slowly, poured it out (like honey) slowly. Wonder if it is the same STP as yesteryear?

The LM Engine Oil Saver is SUPER viscous, as was the VSOT (IF you can still find any).

This is how I do when I changed oil 2 months ago in my E430 with 8.5 quarts sump, I used 5 quarts Mobil 1 0W20 with 2 quarts Mobil 1 0W40, so far it run very smooth, when I add 1-1.5 quarts in summer I may add 0W20 or 0W40 or half&half.

STP or motor honey will thicken things up. But don't get the STP 4 cyl version - it is thinner.
I don't even know if they make STP anymore.

I wouldn't try the thinner oil. I know, some do it and the results are OK, but consider this:
--Better gas mileage helps sell new vehicles
--Thinner oil helps lower gas mileage
--GM chose to stick with 5w30 for some reason, and I'll assume that it was engine life.
--You'll never save enough gas money using 5W-20 to pay for the smallest engine repair.

Schaeffer's # 132.
IMO....For a 2001 GMC truck, I would just buy a quart of Rotella Diesel Dino in 15w40 and add it to the sump. They sell quarts of the Diesel Dino at Walmart.
IMO....You could also splurge for a gallon of Delvac at Walmart, then mail in the $5 off rebate per gallon for about $8 for the gallon. Then on your next OCI, you could, blend up a mix of the remaining Mobil Delvac with some Mobil Super Synthetic for a fine synthetic blend.

Lucas heavy duty oil stabilzer is all u need
STP would thicken your oil, it might even boost ZDDP a bit. I know the older stuff did.
