    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 viscosity is suitable for the 7M...not because it works in your truck.

    Your oil choice is sound, but the logic for using it is not...another case of dumb luck choosing an oil

    I understand. I'm not using because it works in my truck. I'm using it because like u said above the low viscosity when cold. And viscosity when warm. That is why I'm using it.

    I use to to run rotella 15w40 in my truck. I don't know if u guys have diesels but in the winter they don't like to start. With 15w40 it didn't want to start easy. Switched to synthetic 5w40 and it starts with ease at -10.

    5w40 seamed to me that it's the right viscosity for my 7m just trying to get ur thoughts.


    After the engine is rebuilt I will be running a thinner oil because the engine will be alot tighter then it is now.

    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, especially those with higher mileage bearing wear...like yours

    If you're set that you need a thicker oil because of your engine wear, what is your oil psi during cold/hot runs? Your engine might have 140k on it but are the clearances that screwed up that you'd need to step to a thicker oil?

    I'm not trying to be a douche, I'm just trying to understand why you need the thicker oil.

    Oil psi right now is about 4 to 5psi at idle hot. With the 15 50 in it. It right above the zero mark on the psi gauge (stock)

    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 for this motor, a 15W-50 is. It's not going to fix the problem (excessive clearance due to wear or improper build), but it will buy some time. The proper solution is to re-build the engine.

    Just talked to previous owner he said the gauge sometimes didn't work. He said its reads great while driveing but at idle sometimes it reads low. I'm gunna test it with a better gauge
