Anyone Else Experienced This
Discussion
Have just been to collect the Tamora from it's 1K service and warranty fixes.
I was advised by the dealer that they were now using a new type of oil than that previously suggested by TVR. This has been done in conjunction with TVR and TVR Power and as I understand it, is part of the continous improvements designed to improve the reliability of the Speed Six.
The oil is a Semi Synthetic 15W 50 Oil. Apparantly it is likely that when the car reaches 6K miles, this same oil will be used beyond 6K miles unlike the previous arrangement where different oils were used at 1K and 6K.

Well 15-50 is less watery so maybe it does prolong engine life in what is a potentially fragile engine. There are quite a few oil experts on here so maybe they could offer more insight... Anyone...?
I was told (by those close to the factory) to switch to something gloopier like 15/50 when I first noticed I was getting through more oil than the annual knockout-championships of the womens' naked wrestling federation.
It did stem the losses a little, prolonging the inevitable for a while.

From what I understand, an oil with a higher viscosity is used whilst running in. As JSG says, the higher viscosity oil is sometimes used as a quick fix for cars with an unhealthy habit for eating oil, an symptom of impending rebuild doom.
I have heard of particular dealers saying that all types of oil is the 'new oil', including Magnatec...
About a year ago I remember a huge thread about this subject with a lot of help by Opieoilman. He has a huge amount of knowledge which is to be honest above my chemistry knowledge, but it was concluded I believe that the best for the SP6 was the original, 0W40. He said that a semi-synthetic ie, half mineral does not have the same properties of longevity under high temperatures and stresses. Lets face it, the SP6 has both of these, in big doses!
After all if mineral oil gave better performance, millions would not have needed to be spent on researching and creating high performance synthetics?
(Prepares to be flamed for an over-simple hypothesis...

)This is all quite interesting then. The dealer certainly had no concerns over our engine when the head came off.
They basically said that as it was quite a low technology engine (unlike some of the Japanese engine) and therefore was more suited to a less advanced oil. Which reminds me of my other post about using 95 Ron fuel rather than 97/98 required by the Porsche/M3/Subaru we had.

I've been told with both Tuscans that a lower grade of oil is used up to 6k because if the car is run in on a good fully synthetic oil like Mobil 1 it will not bed in properly. Therefore an oil of less quality is used up to 6k and the good stuff thereafter. On my first Tuscan (2003) they changed thye grade of oil at 1k and again at 6k. This time they used the same type of oil up to 6k and then switched me onto the hard stuff.
Guess we will have to wait and see what happens. I should be at 6K by February so not too long to wait.
Certainly the car is running very well now it has had the tappets set and the tune up. I was very pleased that they turned it around within the 2 days, particularly when they had other warranty items to look at. I have heard of some people not having their car back for weeks.

Just to add my tuppence worth, my Tamora came back from its 12k miles service with Mobil 1 15/50 oil in it.
It was serviced by a main dealer who said that they were using that viscosity oil in all engines from 12k miles onwards.
Oil consumption was fine with 0/40 and hasn't really been greatly different with the thicker stuff.

Anyone ever used 'Slick 50' in their Speed 6? Its meant to coat the components with a teflon like coating and reduce engine friction and reduce running temps.
Can also block up oilways and has been alledged to have caused problems in the past. (Try a search) I wouldn't use it without at the very least a written undertaking from the manufacturer of suitability for this engine.
just my 2 pennies worth...but you should never use a synthetic oil in the engine whilst running it in, and its is not advised to switch to fully syn until the engine has done a good couple of thousand miles. otherwise you can get glazing on the bores, which will lead to bad cylinder compression/seal.
