Hi all...
I'm looking for a general consensus on using Castrol Syntec 5W50 oil in a 1 year old Pontiac Vibe (130 hp). The car has 25k miles on it.
I have used this oil in my 12 year old Saturn for quite a while now. The car has 250k miles on it and no problems with the engine. But looking at Vibe's manual, there is no mention of using a synth oil but
10w30 and 5w30. I'm just curious if using the Syntec 5W50 year round would hurt the engine in any way.Thanks
Alex
