I recently purchased an 2017 INFINTI QX50. I have been using Shell V Premium will it be okay to use just premium or regular gas?
I would continue to use premium but most any brand should be OK. I have never noticed anything special about Shell gas.
Will Premium 91 be safe? The dealer says Premium 93 and the cost is ridiculous! I'm sorry I didn't research before purchasing it..
If all you can get is 91 octane it should be good. Read the owners manual for more information but I know for a fact that California only has 91 octane premium and there are plenty of Q50's out here.
