I wanted to do oils and filters on the Landy this weekend. I normally use Comma X-Flow 15-40 which claims to be suitable for “fuel-injected, multivalved and turbo-charged engines”, however, I inadvertently bought Comma XT2000 15-40 which claims to be suitable for “fuel-injected and multivalved engines”, no mention of turbocharged. Should I use this oil, or is it going to do more harm than good?
I appreciate these ‘older’ engines don’t mind so much, as long as there’s some oil there, but I would like to look after the old girl! 200tdi

It'll be fine on it..

Our 200 runs on, whatever i have at the time, a mixture of everything..

It hasn't had an oil change in decades.

Not 100% sure on turbo engines but they say:
Recommended by Comma for applications requiring: MB 229.1, MB 228.3; VW 501 01, VW 505 00; ACEA A3/B4; API SL CF CG-4


By the way did you know halfords oil is made by comma? I often grab a couple of packs when they have an offer on.

Aye, I bunged it in anyway. I’m probably over-worrying as usual. If both oils didn’t mention ‘turbocharged’ I wouldn’t have been bothered.

Didn’t know that about the Halfords stuff, someone has to make it I suppose! Wonder if it’s the same ‘blend’?

The only bits that matter are, A the viscocity and, B the ACEA code, ie A3/B4 the rest is twoddle for old defenders.

A/B: gasoline and diesel engine oils
ACEA A1/B1 Category is removed with the ACEA 2016 Oil Sequences. From ACEA 2012: Stable, stay-in-grade oil intended for use at extended drain intervals in gasoline engines and car & light van diesel engines specifically designed to be capable of using low friction low viscosity oils with a high temperature / high shear rate viscosity of 2.6 mPa*s for xW/20 and 2.9 to 3.5 mPa.s for all other viscosity grades. These oils are unsuitable for use in some engines. Consult owner manual or handbook if in doubt.

ACEA A3/B3 Stable, stay-in-grade Engine Oil intended for use in Passenger Car & Light Duty Van Gasoline & Diesel Engines and/or for extended drain intervals where specified by the engine manufacturer, and/or for year-round use of Low Viscosity Oils, and/or for severe operating conditions as defined by the Engine Manufacturer.

ACEA A3/B4 Stable, stay-in-grade Engine Oil intended for use in Passenger Car & Light Duty Van Gasoline & DI Diesel Engines, but also suitable for applications described under A3/B3.

ACEA A5/B5 Stable, stay-in-grade Engine Oil intended for use at extended Drain Intervals in Passenger Car & Light Duty Van Gasoline & Diesel Engines designed to be capable of using Low Viscosity Oils with HTHS Viscosity of 2.9 to 3.5 mPa*s. These Oils are unsuitable for use in certain Engines - consult vehicle-OEM’s owner’s manual/handbook in case of doubt.

In reality a tdi will run just fine on any old crap!

Oil is a nightmare these days.
Gone are the days when it was a choice between Duckhams Hypergrade “the engine’s choice”
Or Castrol GTX “liquid engineering”

l got stressed about the right oil for my TD5
There’s about ten options
I used a 5w/40 but apparently the SAPS content was incorrect and l had to drain it out and refill with 5w/30

I think low SAPS is for cats/dpf/scr systems, ie nothing to worry about on a TD5.

If you look at the ACEA numbers, A/B categories are petrol/derv, and C categories are either but C stands for Cat/DPF etc.

So wifes car has a DPF so gets C3 oil 5/30, and as mine also takes 5/30 but no DPF, it gets the same simply becasue it is there.

OK so can you recommend me a 5w/40 or 10w/40 suitable for TD5?
The engine seemed a bit quieter with the 5w/40 when l used it last time.

I would assume the engine is Euro 3 same as the early D3? so a 5/30 or 5/40 to ACEA A5 will do the trick nicely.
Have a look at Mannol oils on ebay, seem okay to me, and nowt has blown up yet!

I have tried 5/40 in the D3 and have to say did not notice any difference.

I ran my td5 on truck engine oil 10/40! for 5 yrs and 50k, way to good an oil for a car engine, the same oil used to do 100k between changes in the trucks, truck oils are classed as ACEA E numbers.

I genuinely think so long a you change it often (say 5k) the actual spec does not really matter, as you are not going to be pushing it anywhere near its design limits.

100,000 miles between oil changes on trucks....that’s bizarre as it’s the entire lifespan of most car engines.
Makes me wonder why a car engine can’t be filled with high quality oil and then never touched again.
I guess it’s all the stop start/short journeys that kill the oil in cars.

If you go to the halfords website and look at the oil there's a spec sheet and it says comma on it, I was surprised they didn't take the brand name off it.
