DON'T!
I tried this with my Highlander recently, and the outcome wasn't pleasant.
Mobil 20W50 has been my regular for all the cars rated 5W20, so as I was buying fuel at a Mobil station, I spotted the 5W20 and i was excited to use the OEM recommended oil for the first time in Nigeria. I bought it immediately!
On my next oil change, I took it to the mechanic and did the service normally.
Just about 3 weeks later, I noticed that the oil has dropped from the dipstick!
The mechanic advised that I should topup and then watch it again as there was no leakage anywhere, I did and the shortage continued.
So the mech advised that I go back to the old grade, and that was how the shortage problem disappeared. I never went back to OEM grade!

hmm. . . na Super V 20W50 sure pass. was considering grade change at next service

Thank you Lord

Thanks guys for this wonderful thread. Just got an 04 highlander. First oil and filter change was done today with Mobil xhp 20w-50. Please should I quickly go and drain it and replace it with the recommended 5w-30 tomorrow. U guys have scared the hell out of me.
