Hello fellow oil nuts,
In today's day and age, where oil isn't JUST oil. I have been thinking.
I have a 5L Ford Windsor, which my service book calls for a 15w-40 oil. Most oil companies, when i punch in the details on there database, throw me recommendation's of 5w-40 full synth or a 10w-40 semi synth, some of them offer a 15w-40 mineral based.
My question is, why would it be a better option to go for these thinner oils when the ford service book calls for a 15w?
Keen to know what difference it makes to a engine to go against the service books and put in other weights. As a example - what would happen if the manual called for a 20w and you put in a 10w, 5w or even a 0w oil?
