Even Chaps, merry christmas!

I've been recommended to put 5w-40 Fully Synthetic Engine Oil in my Saxo, when looking at halfrauds to see what was commonly available (not a big fan of buying online) I found that most of this oil was specified as "Turbo Diesel" oil.

I went on Castrol's website and put in my registration plate also to see what they suggested, again it came up with 5w-40 Fully Synth but when I went on eBay for some prices they wre all specified as Turbo Diesel oil.

Is this just to help with marketing or have i gone wrong somewhere?

Castrol Edge for example!

So my question is is there a difference in Diesel branded engine oil, and if so.. what is it? And would that harm my car?

This, why buy Castrol when they always seem to be expensive. You could also put 10w 40 semi synthetic in it as well, wont make any difference but will be cheaper. Also the cheapest way to buy oil is to take an empty container to your local friendly mechanic & get them to fill it up, they buy it in 200ltr drums.

That's a bold statement saying it wont make any difference running 10-40 semi synth as apposed to 5-40 fully synth isn't it?

Opie Oil man told me and all the other VTS owners on the owners club to run 5-40 fully synth (he recommend Fush Titan IIRC but I was just looking around!

+1. Getting the Semi-Synthetic stuff is probably easier though, unless you know people in the trade smile . Regular oil changes is the most important point - you can get away with using any old rubbish if you change the oil every 1000 miles - but using a reasonable quality oil also gives you a safety factor in case of "intensive usage" of the car (eg lots of town use or particularly cold or hot weather) or a delay in changing the oil next time.

I've used GM Semi-Synthetic 10w/40 for years, but only 'cos it was £10 a gallon in my local motor factors. It's now around £13 a gallon - as is Comma Semi-Synthetic 10w/40. No real need to pay much more for a particular brand smile . Just make regular oil and filter changes (maybe every 6k miles or annually, whichever comes first) using a Semi-Synthetic oil, it'll be more-than fine.

I've been running 10w 40 semi synthetic in my Astra van ever since I bought it in 03 at 3 years old, which is what Vauxhall recommended. That Castrol site you linked advised me it needed 5w 40 fully synthetic.

Also on that site they recommend as an alternative for your car magnatec 10w 40 so no, I don't think it's a bold statement at all. smile

5W40 fully synthetic oil in a 1.5 diesel Saxo? Who served you, a monkey?

5w40 full synthetic is what VAG cars with PD engines used.

If you have high mileage; use 15W40 semi-synethetic.

If your car has done less than 60,000 miles, use 10w40 semi synethic diesel oil.

Fully synethetic oil is recommended for modern engines.

PS: I'm not an idiot, I used to have my own motorfactors store and am fully up to speed on engine grades and what oil goes into what car.

Castrol is top notch but you pay a lot for the marketing of it. Castrol Edge for example is now one of the biggest sellers in the US where getting an "edge" over your competitors is required.
We sell Castrol,Comma and a cheap brand. I use Comma as quality wise it is good at a reasonable price.
The previouse advice looks okay without looking at the spec sheets.

with respect, I am not sure you do know your grades...

there is a significant difference between a 5W40 and a 15W40, and (especially at this time of year) a 15W is going to make cold starts/running somewhat worse (not forgetting the knock on with fuel consumption).

Proper synthetics (as in not halfrauds stuff etc.) cannot really be compared to the normal semi-synth cheap stuff, that said, the real answer is pick the right oil for the engine and use it's going to get.

Oil life is down to several factors, for example, if you race an engine and the oil temps are regularly well over 100C then a fully synthetic oil is a better bet as it will not break down, conversely, if your looking for a long service life, you need a good oil with additives that can deal with combustion gases (and not get sludge'ed up or overly acidic).

in this weather, the last thing you want is an overly thick oil, your oil temp is never going to get close to 100C so having a 15W40 oil is going to really be an issue, hence why most makes recommend 0W40 or 5W40 for UK use.

Mobil-1 and Mobil-1 Turbo diesel is widely reckoned to be the same oil in different containers. The data sheets are identical. Both carry the same Mercedes approval, MB229.5.

so? that does not make them the same, they just meet the same spec.

Diesel oil has to deal with soot from combustion, if they don;t have the right additives to deal with this, then the oil turns very acidic quite fast, thus engine erosion/wear is accelerated.

Read all three points, not just one of them.

The MB point is the Mercedes approve the "petrol version" of Mobil-1 for use in their diesel engines (as long as they don't have a dpf).

Castrol Edge Turbo Diesel 5w 40 is the oil of choice for the S2000. Castrol themselves even confirmed that the TD element is just a marketing thing.

No I don't have a 1.5D, I have a 1.6 16v Petrol Engine. Thanks for taking the time to reply but I was looking for whether the label stating "Turbo Diesel" was any different to any other oil, which it would appear it is only a marketing ploy.
