Right guys and girls annual service this weekend on the old girl. For those who don't know me she's a 1980 Mk2 Granada 2.8 V6. I've been on various online stores and I'm getting conflicting information on which to use. Any suggestions or ideas on which is better or are they much of a muchness?
Cheers
Dan

Instinctively I would have though 5w30 was a bit thin and modern for the V6, without checking specs I would have thought at the time a 10w40 or 20w50 was recommended, if its 20w50 I like valvoline VR1

There may be an owners club, if so ask on there as they'll know what works and what doesn't. |

You don't have to guess with oil.
Your car would have had a recommended viscosity rating from the manufacturer. That is a start at least, but of course oil technology has come on a long way. A semi synthetic multigrade will flow from cold much better than a multigrade mineral oil which would have been original, for example. You may want to get an oil with high levels of zinc too.
The 2 oils you mention are quite different, I would suggest calling the technical team at Millers oils. I did that only last week and it was really helpful.

As it turns out I've been pointed in the direction of a 20/50 - thought this would be way too thick but apparently it's perfect...

The SAE is not an indication of how 'thick' or 'thin' an oil is, it's an indication of it's 'propensity to flow' at certain temperatures .. .
. . . with apologies for being pedantic . . .
