This has to be a former member having some fun. No way he/she is this clueless.
So again. You’re saying oil thickens when heated?Read that SAE J300....
Winter rating....
You said weight in that other post.... And were patently wrong.
It reads.... 10w30...
10w for winter.... Cold rating tested per SAE J300...
30 operating viscosity.... At motors operating temperature....
Most of these statements are incorrect.This is not true. Again, i cannot stress this enough. Viscosity at temperature is about the quality of the oil you buy. While its true that a 0w20 COULD perform better its a deceiving way to looking at it. A 0 weight oil does not necessarily flow better at cold temps than a 5 or a 10 weight oil. Both oils have a 30 rating in Winter (plus or minus the differential of the base oil). The 0, 5, 10 viscosity represent the characteristics of the oil as the oil heats up.
Its a far better idea to provide youre engine with the lubrication requirements at operating temperature (where far more wear occurs over time) than it is to focus solely on starting. Here in Canada - if youre starting youre car in -30c. Plug the thing in.
I see what you mean. This guy's an absolute squirrel. Claims to be a certified lubricant specialist working for a lubricant formulator, but doesn't understand the basics of SAE 300. But he is exceptional in one sense; he's alienated the population of BITOG in only 12 posts.It all started here.
Certified oils
Has anyone used an oil from certified labs. I have some certified labs 5w30 syn and my brother uses there 15w40 . He swears by there grease but they are kinda expensive.bobistheoilguy.com
Maybe get really really simple …So again. You’re saying oil thickens when heated?
That it rests at winter weight of 10 and then increases to a viscosity of 30 as you heat it to operating temperature?
I’m really trying to spell this out for you in the simplest way I can think of.
