I have recently found out my car is burning M1 0W40 oil, i figure its because it is less viscous when cold compared to a 5w30 oil(i tend to go past 4k on accident when oil is not up to temp when getting up to speed on the highway) so i kind of figured i should change back to a 5w30 oil and see if im still burning oil before i take my car in for an oil consumption test(and i wasnt burning oil with nissan's ester oil)

i burnt approximately half a quart in the last 2k miles(which im not sure if that is normal but i dont remember burning that much with nissan's oil) because when i say i was a bit low on oil i poured half a quart in and i was just a tad under the high mark

I want to go with an ester based oil since it is recommended for the car, so my question is what does everyone recommend that is not too expensive, I know about redline which everyone uses but they are kind of hard to find in local automotive stores and id rather not wait for oil to be shipped out to me

I know royal purple is a ester based oil but from what i have heard is that royal purple turns to **** after 3k miles

any recommendations would be greatly appreciated

Thanks
