Am I right in saying that the vectra c 2.2 sri direct takes fully synthetic oil 5/40.? Or have you guys recommend something else . Millage is 119000. Mick
-
Thought it was 5w30 fully sympathetic
-
Either semi of full lymphatic. But given the more sensible short changes that are considered good servicing, I don't see the point in the more expensive full lympfnode tbh.
-
plus the semi will be more likely to stay in the engine on an older car than the slippery full fat stuff :y
-
Yes if going for the oil filter collapsing 20k changes, go full uthinasia. Defo. :y
-
Thanks I'll get a tub of semi synthetic then and filter. And possibly flush it out as well to be Certain it's clean .
-
Steady with the flush. It can clog the arteries and the oil pic up. Better to change it for semi synthesiser for a few k, then fit the fully uthinised after that, with new filter again.
-
plus the lifter treatment to clear a bit more shite :)

it is and that is what Vauxhall states should be used :y
-
At the garage we use 5w30 semi and 5w30 full fat. Semi goes in old cars and shite boxes, fully goes in nice cars. Simplez ;D
-
Semi being 10w40. Fully being 5w30. For GM spec.

Fully sympathetic would be better in higher mileage cars as it holds its viscosity,better than semi.

Nope. Fully is thinner. From the outset. Another reason why 10w40 is better on higher mileage cars...for omegas. Certainly.

Using oil that's to heavy in a car recommended to use a 5w/30 can cause sludge issues.

That's my understanding hence the garages approach :y

and In the end causes the timing chain to snap :y

fully syn 5w30 no thinner than 5w30 semi, and as said fully synth will maintain its viscosity better (longer) than a semi. bad practice to use a thicker oil than manufacturers original spec.
-
Of the same grade, yes.
But GM fully and GM semi are not the same grade.
I was talking about that, not tother.
