Engine oil?

[ginger948cc]

I'm about to do an oil & filter change. I have Castrol GTX  10W-40 which is what I used last year. However ,it does say that it is for modern engines . I think I saw one for older engines. What is best? Thanks for any comments.

I use the 15/50 mineral based stuff from Halfords, it says it is for pre 1980 cars, works for me !

I would go for a 20w50 of reasonable quality. I like Duckhams 'Q', but there are plenty of others of equal or higher quality.
Cheers,
Bill.

I have Duckhams Green 20-50 in the Herald (Mk4 spit) and Valvoline racing 20-50 in the 1500 dolly, Valvoline are now doing a 10-60 which interested me

I find the best oil to use in old cars is the one that will wash off the driveway easiest otherwise the missus gets upset.

I'm into Duckhams Q 20/50- however on the saloon I will be going the synthetic route as the old thing does not use oil. The GT6 does and will stay on Q.
I do not like the idea of using 10/40 in an old car.

I set about getting some Duckhams Q 20/50 today at Halfords in Croydon........they don't stock it!

Phoned 3 car accessories shops in South Croydon.....still no luck!  Finally successful at "Motos" 133 Godstone Rd.  Kenley. (if anyone else has problems locally.)

Consuela is now purring contentedly.
