Yes TimmyTim, as tfb says, I thought there was a similarity between ECP and CP4L sites as if they were the same company, and same address in London came up. Oh and too the fully synthetic I thought you had mistaken fully for semi as I could only find the semi which my car is running great on just now.
As too the ABS light I think I have your answer so follow my next thread as my car prepares for MOT next week.

 

TRIPLE QX 5w40 Fully Synthetic Engine Oil 5Ltr

This is what I've got in my Gt4 205. It will be going in the GV on my next oil and filter change.

 

The 5W fully synthetics are too thin for these engines. You'll get a drop in oil pressure and may see oil leaks. Stick with semi 10W-40

Watch out before you start a whole new religious Oil discussion
A lot of people will disagree with you on this.
I followed a LOT of discussions and did a lot of research on this issue, and dropping oil-pressure and leaking seals due to synthetics are mostly something from the far away past and if an engine starts leaking from Synth oil its only because the oil reveals an already existing bad seal.
Overall good synthetic oils are superior to good (semi) minerals, especially on modern engines and our engines are modern engines.

 

Motorfactors quote Semi but its up to oneself on what you want to use, as long as its not ordinary oil.

 

I have Mobil 1 Turbo Diesel 0w-40 in our GV. On the Mobil 1 site there is an oil recommendations that list oil for my car. I have no leaks what so ever on my engine using this. If you look at the specs of this oil you'll see it has a very goog TBN (Total Base Number for anti wear) and the VI (Viscosity Index ) is very high, so is the Flash point and a very good low pour point.

As pointed out by my friend. A synth will not make oil seals fail ( Unless on a very old car with seal that can react to synth base fluids) the truth is that they already have done so! But people think its the new synthetic oil.

The big problem you have with a semi -synthetic engine oil is you just don't know how much full synth is in there! Could be 5%- could be 25%. These oils can't compaire or compete with full synthetic when it comes to protective qualities! There are also Ester and double Ester oils like Motul 300V that takes it to an even higher level again with these group 5 oils. I have a load of that oil im my garage! Think it might make its way into my GT4 @ some point.

 

Btw... Mobil 1 New Life and Mobil 1 Turbo Diesel 0w-40 engine oils are exactly the same oil! But in a different container! Mobil informed me that people who have a diesel car like to see that on the tin! Marketing boys eh! I bought a load of the stuff from Costco for £15 for a 4L can! So made away with over 100L of the stuff! I did the same when they were practically giving away Castrol EDGE 507 00 spec oil for £9.99 for 3x1Ltr containers...

 

This could so turn into an oil thread! Lmao

 

I really wouldn't use a semi in a Turbo Diesel motor. The Turbo bearings can reach temperatures of 900 degrees! If worked hard! A semi oil is just mineral oil with some synthetic stuck in...
