Yeah, changing the viscosity is fine depending on the climate you drive the car in.So I'm curious, is 0W-30 fine for our cars? From what I have been reading, it seems like it might be better(?) but I'm not exactly well versed in this stuff.
The reason for asking is that it was listed as the product used for my last oil change at the dealer. I also figured that being in California probably means that I never actually test the lower temp limits of the oil anyways.
The first number in the viscosity grade is the low temperature, winter rating (i.e. 5w and 10w). In fact, that’s what the “W” stands for: Winter. So, in warmer climates, you can actually go up in the first number, like 10W-30. Is it safe to use a 0W? Sure, but a 0W can get colder before it gets too thick for the engine to pump than a 5W or 10W, so in warm CA that doesnt usually see freezing temps, why use it? That first number is mainly for startup because all oils warm up to the same viscosity rating as the second number.
I also drive a RAM Ecodiesel that recommends a 5W-40 for winter in cold climates and a 15W-40 for summer, warm weather climates.
