I plan to use Mobil 1 with my CX-9. I've always used 5W30 in my X5 (per manual), but from what I read in the CX manual, it's recommending using 5W20.
When I googled, it seemed the newer car (my X5 is only 5 years old, what were they thinking?) these days run on 5W20. I'd hate having to label them separately and since I buy in bulk, I don't like to carry both of them.
Can anyone tell me or point to sites that can explain, can I safely use 5W30 for both cars or should I switch to 5W20 for both cars?
Thanks.
