Which oil for Aston Martin V12

[MaverickV12]

I am looking at changing my oil again and this post is related to the V12, because I don't know how the V8 reacts. I have looked at the manual and as you can see from this high definition crystal clear photo......



It recommends the 0w-40 Mobile 1 .....



From what I can read about the 0 is not related to the oil in operating temp at all, it is only related to the ability of the engine to be cranked in low temperatures, it is the higher number that is related to the normal operating temp. I have been talking to some different people and they are saying that the 0w-40 is quite a thin oil, and to use a more thicker oil to keep the engine relatively quiet.

What people are telling me, and I'm agreeing with them, is that the V12 runs quite hot, the temperature gadge is clearly running at normal temp, but the V12 produces huge amounts of heat. In the Winter the V12 is great as the car is hot and snow does not build up on the bonnet for long and in the summer the AirCon just fights with the heat soak that the engine produces.

So I have just used this ......



But now the weather is turning warmer, only just, I'm looking at using (Mobile 1 still) ........



The lower number of 10 easily falls within the temperature range of our country and the higher 60 number will run better with the hotter V12 engine. In the old days, people used to have to change oils in the summer and winter and then in the 1970's (I think - can someone confirm when?) someone had the idea of All Season Multi Grades, then with the advent of Synthetic oils the variation of the scope of cold crank and normal operating temp was expanded all within one oil.

The 10w - 60 oil states the oil is for motor sport applications.

Would love to hear your comments on the use of 10w - 60 oils in the V12 and indeed in the V8, but I don't have any experience of the V8 ......

Maverick, you need to speak to a triboligist. He'll give you the right pills!

Mobil 1 0 - 40 is recommended by Aston, I would not use any other oil and I am sure my engine runs hotter than most

If you are not an oil expert or have not spoken to an expert and your mate down the pub does not qualify, then why on earth would you not stay with the oil that is recommended ?

[George29]

Just use the recommended stuff! Are you hell bent on destroying your engine? You certainly seem to be trying hard to do so.

I think the 0/40 has more flavour than the 10/60.

As usual...it's all down to personal taste

Do they? The manual recommends Mobile 1 ........... and then in brackets it says (0w-40)

It looks like AM recommend Mobile 1.

On the right of the page, there is a detailed chart of ambient temp and the corrolating thickness of oil that they recommend, the chart does not even go down to 0W, it starts at 5W with a minimum temp of less than -30deg, the 10W starts at -20deg, so for this country the -20deg will easily surfice (well in the West Country at least).

So do AM recommend different oils for different temps?

The clue is what is in the brackets

I also checked the mobil 1 website and it recommends that oil also.

Have you tried asking the Oil Man?

His/their advice has been pretty good in the past for lots of different types of cars over multiple forums.

I'll give it a go. Thanks.

OK, its not instant, I thought it was, how long do they take to get back to you?

Well, for starters, you might have to wait for them to get into work tomorrow...

You mean a human reads it? Thats fantastic, we might even be able to enter into dialogue ...... ? As opposed to, "Computer says No".

In the offical AM dealer, in MAdrid, they use CASTROL 0w30 . I have a DBS, I told them that manual recommends Mobil 0w40, but they tell Castrol 0w30 is a recommeded oil as well.

This is a little confusing as it says that this oil is recommended for Aston Martin, anyone know of Castrol Edge being recommended for AM ...... ?

Wait, Wait, Wait, it says, "trusted to perform", what does that mean......?

Matias - 30 grade oil sounds a bit thin, especially for the ambiant temp of your Country, I'm assuming that you're not driving in snow ....

From what I can gather thinner oils are used for better fuel consumption, I just read an article about 0w - 10 oil that can save up to 6.5 mpg, but whether I would put a coupe of gallons of 3-in-1 in my car to get 6.5% better fuel economy is questionable.

I found this as well .......
