I use distilled water with a few drops of Dawn, a small silicon squeegee and a microfiber towel. Works much better than anything I've tired and the quickest. I've tried many glass cleaners, alcohol etc, and this method is the best by far.
Valvoline says the oil is also their top choice for new engines, so why wouldn't they have it approved for Dexos 1 Gen 3, thereby expanding their potential user base?
I emailed Pennzoil in the last few days and they said there is no schedule to update the bottle or PDS to indicate that it meets Ford WSS-M2C61-A1 spec. How hard can it be to complete this? It tells me Ultra Platinum may be on the chopping block, although I hope not as I've used it for the last...
Thanks to everyone for the advice; I've decided to go with QSUP. Hopefully, PUP will be approved for Ford spec WSS-M2C961-A1 before the second oil change.
