Hello all as the topic says I drove my 1997 Ford Probe GT 2.5L v6 2400 miles from Pennsylvania to Arizona in two days pretty much non-stop. My car has 164k miles automatic transmission and calls for 5w30 oil. I have been using 5w30 pennzoil hm 3k changes since I bought the car about 40k miles ago. I recently changed to Pennzoil Ultra 5w30 for three oil changes and love it! Main reason for this topic is I moved from Pennsylvania where its 10 degrees winter and 90's humid summers to 120 degree dry never below say 50's will 5w30 be fine in the extreme heat in Arizona summer? I have about 2000 miles till I can send this sample out to test it at Blackstone to see if i have any issues or if i can go longer intervals. Car has new water pump and coolant never overheated ever either.
Would love some input from some experts here
Thanks,
Brett
