All 3 of the Mobil oils you listed are Grp III hydrocracked oils...not that they are bad oils, they do not meet the definition of a true (PAO or Ester) synthetic. If you are going to run a Grp III, I would choose Pennzoil Platinum or Ultra...both have better add packs than Mobil One...use...

It will, but it also will take a very long time....I'm talking about when the additive pack starts to deplete, at 10-15K miles. PAO oils hold their viscosity quite well. Look at the oil analysis thread, virtually every oil is in it's viscosity range at a 5-6K change interval...and even that...

Mike has used Royal Purple for years with good results, and has oil analysis to back it up...if RP works for your car, I say don't fuck with it. I would use the 5W-30 version though...

You're welcome. Castrol Edge is a good oil...so is Pennzoil Platinum or Ultra...Royal purple is also good, but it's additive pack is not as good as the previous two.

Changing after 500 miles was fine - you did no harm. Using a heavier weight oil will reduce flow through the engine, even in the summer months. An oil with the lowest possible 1st number is desired (cold viscosity) with a 30 as the 2nd number...i.e. a 0W-30 or 5W-30. This will get max oil flow...

That has zero to do with it.... Read the rest of the thread.

Pretty sure that contains friction modifiers for an LSD...not good for a R154.

T6 would be an excellent choice in Houston and less expensive than my 2nd choice, Redline 0W-30. Redline 5W-30 is excellent as well. You won't go wrong with any of the three. ;)

Do as you will...personally I don't see any benefit. The KISS principle is alive and well...what I see in that diagram is additional failure points...

That's what I think and why add that level of complexity for very little gain, but what do I know... ;)

Moved to proper section. The oil change has nothing to do with the coolant low light...

Why would you want to add heat to a cooling system that's at it's limit?

You're wrong...

Strike Hold contains Tetrachloroethane, Hydrotreated Naphthenic Distillate, Bis(tridecyl) Adipate, and Phthalate Ester...the first is a solvent, commonly used in dry cleaning (very toxic), used in tis case as the carrier since it evaporates so quickly. The 2nd is a light lubricant with solvent...

Mechanical gauge, measured at the block...

V100 = viscosity at 100 deg C...yours is right inline for T6. µ refers to particle size in microns - anything smaller than 10 microns is generally considered insignificant, but the density of the particles (regardless of size) is important to determine overall oil cleanliness. That's where the...

It's a 2001 7.3L...I really like that motor ;) Bearing wear will cause pressure to drop...his psi indications show it. In this case, a slightly thicker oil will provide a better surface to minimize metal-to-metal contact between the bearing and the journal. A 5W-40 is not excessively thick...

Now you're making a little more sense ;) I do have a diesel truck and I bet you can guess what oil I use ;) It doesn't get terribly cold in Phoenix, but it does in Flagstaff...my powerstroke is the same cold natured beast you described. T6 will work great in any of the Supra motors...

If you are referring to GC 3W-30 as a "thin oil", that simply is not true. GC hot viscosity approaches the 40W range. GC is not thin by any means T6 will work (and work quite well), but not because it works in your truck. It will work because T6 has a fairly low cold viscosity and it's hot...
