Its already getting warm here in AZ, 90 this weekend.


Everything on my SUB is tip top. Tune, tires, fluids.


I have been toying with moving up in engine oil weight from 5w30 RP to ?


I always drop in RP ICE.


What else would you all suggest?

 

Wish I was there. Been looking at houses in Lake Havasu City. Love to boat.

I wouldn't do anything. 90s hot for humans, but your engine is already way hotter. if it's 90 or 100 or 60 out, does it really care?

 

That's always a good point. MY 2003 Denali seemed to suffer from thin oil and a drop in OP.


I use syn for the heat reason, my concern is the ambient air of 100+ and ground air of 120+, lots of black tar roads here and the ground air plus stuck in traffic really cooks engine fluids.


I have seen RP ice work well, because we are so dry here lots of static builds up on cars and radiators. So the ICE works well for that.


Tires don't last long in AZ heat. They disintegrate quickly.

 

interesting to know. AZ is where many of the Explorer/Firestone blowouts were.

I bet you don't have rust though!

 

I would just stick with the recommended 5w30. I've been running 5w30 mobil 1 since day one here in AZ and now have 171k on my 07 Tahoe.
