I went to the dealership today for an oil change on my "07" impala w/5500 mi, I supplied the goods with 5qts PP 5w30 / wix o/f and a/f , All went well except that I forgot 1qt of 5 qts of PP (it takes a little over 4.5 qts), so the tech put in 1/2 qt of what they had in shop to complete the fill. I would think they used M1.. Big deal or not? I was going to do an UOA on this fill ..
And is PP a good oil to use when I go by the OLM or is M1 a better choice next time ?
Thanks for all your advice ! !
