Well congrats on your Q purchase and welcome to NICO! What is it exactly that you need help with?

have a 91 Q45a and it has a 136,000 mile, about to do a oil change and want to know which is the best oil to use

I prefer Mobil 1 full syn 10w40 or 10w30 if it gets cold, however I am not the expert. Do a search on oil as we have had experts post extensively on the subject.

thank you

Yeah, just do a search for "oil" in the recent *and* archived threads. Put in "Palmerwmd" as the thread creator. You'll come up with more oil info than you ever asked for

Welcome into the best knowledge base for the G50 Q45. Do you have your car's dealer performed service history? Get to know a good service writer at Infiniti of Kirkland very well.

You will want to read the Articles Forum for starters, and then all posts by Q45tech and texasoil before doing much more, like starting the engine again before checking the timing chain guides. Really.

Have fun!
