Oil change time coming due for my Terrain. I've used PP in the other vehicle which I no longer have. My trepidation is from
the fact the Terrain is DI. I've read that oils with low volatility #'s are better. Quaker State 5w30 Ultimate Durability is a 10 according to PQIA 2016 test results. I consider wear protection and cleanliness top priorities, but PP and Mobil 1 have much higher Volatility 13-14 if I remember. In the last 1800 miles I did have to add about 20 oz. to top it off. So, If I'm going to have to be adding make up oil now and again, I don't want expensive like Mobil 1. Its like $7.98 a quart at walmart. Quaker state UD looks better price wise, but will it keep the engine clean? I bought the Terrain used this past July
with 42,000 miles on it. Was wondering if I could get the rings cleaned up some with Quaker state UD 5w30? I like to change my oil every 6 months, usually
May and Nov. Current fill is Pennzoil Gold 5w30. Thanks for your time.
