Hi all,
Great to be a part of this community, very impressed by the dedication to engine oil. I have two questions for you oil experts. I have a 2005 325i with 150k km. This is my first German car and first car that requires synthetic oil. I've already figured out that I should use LL-01 certified oil. Choices are limited where I live. I was able to find Castrol EDGE 5W40 LL-01 certified oil on sale and used it for my first oil change.
My question is: is the 5W40 oil too thick for Canadian winters? Is there any negative consequence of using this oil in the winter? It gets maybe -25 Celsius here on a really bad day. Usually it's not that cold though and it's just a few degrees below zero.
5W40 Castrol Edge LL-01 certified is:
100 degree viscosity is 13.9
40 degree viscosity is 82.6
0W30 Castrol Edge, which is also LL-01 certified, is a bit thinner. I didn't see this oil in 5L jugs though.
100 degree viscosity is 12.21
40 degree viscosity is 72.0
Mobil 1 0W40 is also readily available here:
100 degree viscosity is 13.5
40 degree viscosity is 75
All these oils are LL-01 but the viscosity varies a bit. Does it matter which one I use in my DD?
Second question is: what kind of oil change interval should I follow? I drive about 10-13k km per year. Mostly short trips. So I was thinking once a year or 10k km on synthetic oil should be good.
