Oil recommendations for high temp 100k plus 4.0 engine

The Redline MTL cost me $36 USD a quart this morning what does it cost there?

64 for 4quarts

I actually have 2 left over (only need two for the NV3550’s) I’d post it to you, but it would probably cost an arm and a leg

I cant seem get high mileage 10w30 here high mileage oils start at 15w40.

Thats what im saying, a specific high millage oil is not necessary, any 10w-30 NON high millage would work, hell any sae 30 would work too.

I only use high mileage because of the seal conditioners which stopped my very small RMS leak. If you need the seal conditioners maybe you can add them separately, if you don't just use any 10W-30. I only use conventional, but to each his own.
