Oil!

No - I meant the beginning of the long rambling thread over synthetic v mineral v semi-synthetic, Mobil 1 v Castrol v Tesco's own, thin oil passages v wide oil passages, oil leaks v no oil leaks, which "weight" range, what is a weight range...
Do a search over the whole forum for "Oil" and you will see what I mean!
Nothing wrong with asking the question, I was just spotting the beginning of the well-trodden path.[]
Let's kick off with an important question, is it a 924, 924S or 924 Turbo?

]Let's kick off with an important question, is it a 924, 924S or 924 Turbo?
When I bought my 1st 944 2.5 from Hartech I was told Synthetic is too thin for it. Advised to use Duckhams Hypergrade if I recall correctly...
Of course a few years have passed since then, but I would tend to agree - semi-synth is a good bet.
Any other opinions from the 924 community?
Might be worth looking on the 944 forum as you have the 944 engine there - I'm sure there has been a lot of discussion on oil there fairly recently.

I've been using BP 0W/40 oil in my 2.0 up till now, but after reading the article on page 100-102 in Novembers 911 & Porsche World I will be buying some 15W/50 Mobil 1 for my car.
I was wondering though, will I be able to top up with the new oil into the old with no problems?

I went through this a couple of months ago and did a fair amount of research on the subject. Yes, it is a well trodden path but there has to be a first time for everyone. I'm not sure that just because an oil is synthetic, it is too thin; I believe that it is the viscosity that matters here. The two numbers quoted eg 0w-40 describe the viscosity at low and high temperatures respectively. The first number should be low as this determines how quickly the oil will get to work at low temperatures. The second number should be high as this determines how much it will protect at higher temperatures. There are other factors to consider but I'm going to stick to viscosity here. For more, see this MG website:

I was using Mobil 1 0w-40 and found that this was too thin. After doing my research I narrowed it down to Mobil 1 15w-50 and Castrol Formula RS 10w-60 both being fully synthetic oils. I went for the Castrol as it had the wider viscosity spread thereby getting to work quicker at low temperatures and protecting more at high temperatures. I've been running the Castrol for almost a month and I am very happy with the results so far.

This is indeed a subject which has been done to death, but for a very good reason.
IMHO the manufacturers are largely to blame. There is an needless proliferation of types and weights on sale, with competing, contradictory, and confusing advertising claims. I reckon a lot of the myths and legends have been whipped up by the manufacturers. One reason I like Halfords is that they tend to make clear which oil is best suited to what type of machine.
Let me remind you of something else ... longevity. Go dig out a car magazine from the 80's and look for one of the early Mobil 1 ads. The key selling point back then was that synthetic oil lasted for 25,000 miles without changing. Whatever happened to that claim? Very conveniently forgotten huh?

It was only a light hearted comment[

Paul, it seems like you can make the switch now but I don't think that you're going to notice a difference simply by topping up with 15w-50. It may be worth continuing on with your BP until its time for an oil change and then switching over to the thicker oil. That way, you don't waste the BP that you've got left and you get to notice the benefits by doing a complete oil change.
By the way, shop around on the web for prices. In know that these guys are quite good for Mobil 1:

As I mentioned in my previous post, I prefered Castrol formula RS 10w-60 and found it was cheaper at my local motor factors shop than on the web. Prices I saw ranged from £26 to £35 per 4 Litres.
