sounds like you have a sedan, so also what you could do is to just get the wheels barely spinning and hold one rear wheel to put some load on the engine and help bring temps up. keep it over 160F at all times even if you have to hold a hairdryer on it the entire time.... you may need a second person to help.
That wouldnt be so great for the clutch of diffs. Cyrul states to make sure the wheels arent spinning , therefore no clutch engagement.
The fuel is putting load on the engine and the rpms arent so high so this really wouldnt be needed either way.
At least thats my thoughts on it.
