which oil to 7A engine

[Tom_]

which oil do you use in your 7A engine? thanks

[Error404]

5w40 synthetic for me

[iain1067]

too thin imo, 10/40

[Flat on my back]

This one...

Fuchs Supersyn 5w-40, and damn cheap at GSF!!!

as recommended by OPIE oils.

[20Vcqdriver]

oil

Castrol magnatec 10w/40 and occasional addition of slick 50. Always ran well with it.

[Acidburn]

I'd also agree with the 10w 40 tbh think 5 is a bit thin.

[caliper]

I've used castrol 5w-40, very bad. then i tried castrol rs 0w-40, much better, today i changed it shell 5w-40, don't know yet.

caliper : so some new experience with shell 5W-40 ?

[Error404]

5W-40 is best in winter and if you use the car on relatively short journeys (>15 mins) becasue it is less viscous it will provide better protection from cold and under cooler running conditions. 10W-40 will be fine in the summer or if using for longer journeys.

Far more important is the quality of the oil used IMO

[Tom_]

and which brand oil do you use?

[Tom_]

and what do you say on 5W-50?

[Tom_]

some more experience?i will be pleased for each one ...

[dubmeister]

Viscosity depends a lot on the mileage of the vehicle- 5w50 too thin for anything over 100k, 10w50 better bet. IMO

But as said previously, quality oil is far more important (fuchs/mobil/castrol) and before every oil change use a flush and
OE filter.

cleans all the old **** out!!!

5w40 for me as I do short journeys and crawls sometimes.

Next would be 10w50

Haven't found a single good 10w40

There is no correct oil just the one that suits your driving best.
