I want to take my Gen1 to Penfold mazda for a service because i have used car warranty with them, also because i don't have time at the moment to service it myself + they will give me a loan car.
My car has 107,000 on it and Mazda say that they will be putting 5w30 Valvoline Fully Synthetic engine oil in it as thats what they use for all cars they service now.
Has anyone had any experience with this oil/know whether it's good?
I don't want to have blue smoke issues etc. I would have thought 5w30 was too thin and i was thinking it should have 10w40 in it...
opinions? I know there is a massive thread about fluids on here somewhere but i really don't want to be reading through 200 people's answers who don't even come on here anymore and i know there are still a handful of wizards on this forum who i am looking to for the answer @SarcasticOne ^_^
