Just bought a 2017 Buick Envision. Nice car, great deal. Surprisingly made in China with 98% Chinese parts content. Engineered and designed in Detroit. Here's my question. The owners manual plainly states to use Dexos 1 5w30 with AC Delco Syn Blend recommended.On the engine fill cap it states Dexos 5w20. Dealer says all they stock is 5w30. What weight do you think is best?
2.5 liter 4 cyl engine with 197 hp. Interestingly, have the same engine and drive train in my 2009 Malibu and it takes plain old dino 5w30 and doesn't use a drop.
