Has anyone had experience of these offers for a Diesel. I ask because it's 6k change time on my Mondeo TD ( 97) and for the price they charge it's not worth me getting the overalls on. £15 for Hypergrade or £20 for Semi Synt QXR ( Duckhams ?)BUT are these oils suitable for a Diesel?

Most oils have both petrol and diesel ratings which are labelled by their API or ACEA ratings. The ratings are as follows but at those prices, you'll be getting what you pay for.
API = American Petroleum Institute
S = Service - Petrol Engine Performance
C = Commercisl - Diesel Engine Performance
PETROL
SG - Introduced 1989 has much more active dispersant to combat black sludge.
SH - Introduced 1993 has same engine tests as SG, but includes phosphorus limit 0.12%, together with control of foam, volatility and shear stability.
SJ - Introduced 1996 has the same engine tests as SG/SH, but phosphorus limit 0.10% together with variation on volatility limits
SL - Introduced 2001, all new engine tests reflective of modern engine designs meeting current emmissions standards
DIESEL
CD - Introduced 1955, international standard for turbo diesel engine oils for many years, uses single cylinder test engine only
CE - Introduced 1984, improved control of oil consumption, oil thickening, piston deposits an wear, uses additional multi cylinder test engines
CF4 - Introduced 1990, further improvements in control of oil consumption and piston deposits, uses low emmission test engine
CF - Introduced 1994, modernised version of CD, reverts to single cylinder low emission test engine. Intended for certain indirect injection engines
CF2 - Introduced 1994, defines effective control of cylinder deposits and ring face scuffing, intended for 2 stroke diesel engines
CG4 - Introduced 1994, development of CF4 giving improved control of piston deposits, wear, oxidation stability and soot entrainment. Uses low sulphur diesel fuel in engine tests
CH4 - Introduced 1998, development of CG4, giving further improvements in control of soot related wear and piston deposits, uses more comprehensive engine test program to include low and high sulphur fuelsSG - Introduced 1989 has much more active dispersant to combat black sludge.
ACEA Specifications
(Association des Constructeurs Europeens d?Automobiles)
ACEA ratings are prefixed with ?A? for petrol, ?B? for light or passenger car diesel and ?E? for heavy duty diesel.
The current specifications are:
A1 Fuel economy petrol
A2 Standard performance level
A3 High performance and/or extended drain
A4 Reserved for future use in certain direct injection engines
A5 Combines A1 fuel economy with A3 performance
B1 Fuel economy diesel
B2 Standard performance level
B3 High performance and/or extended drain
B4 For direct injection car diesel engines
B5 Combines B1 fuel economy with B3/B4 performance
E1 Non-turbocharged light duty diesel engines
E2 Standard performance level
E3 High performance and extended drain
E4 Higher performance and longer extended drain
E5 High performance and long drain plus API performances

Atention Moderators:
Could we make this oil specification information sticky?? This excellent and up to date information should be used to assess oil quality rather it being judged on brand or price.
Maybe that way we could avoid the regular 'what oil should I use' debates.
Just a thought.......

Done.

Thanks DD
Should add some value to the Forum for all to read.

If you visit the National website:
www.national.co.uk
and check under Specials, you'll find the oil and filter change is for vans and cars up to 2300cc, but excludes diesels. However, the newspaper ads (also shown on the website) state "Any" car or van up to that capacity...:-(
I've been using the Ormskirk branch for semi-synthetic oil and filter changes for my Bora (£15 using the special voucher in the papers or printed off the website), but this has since gone up to £20. Still cheap.
The work is always meticulously done and takes about half-an-hour.
As the Ormskirk branch is unable to do MOTs due to its layout and facilities, I use the Lyons Lane, Chorley outlet. Again the work is carried out in exemplary fashion, any potential problems which may rear their head in the future are pointed out and the MOT, again by using the voucher, is half-price. Tesco Clubcard points as well...:-)
National informs me by post annually that the MOT is due in the near future and repeats its half-price offer. So far it has cost me about £2.50 in petrol to get to Chorley and back each time - well worth while at a saving of just over £20 for the test.

My Bora is the 1.6 petrol engine version.

You find that some places do not drop the oil through the sump, instead sucking it out through the filler. This is potentially bad for your engine leaving any sludge or dirt in the sump thus contaminating your new clean oil.
Not sure if this is the case with these but worth bearing in mind.

On one of the USA MB owners forums they took the sump of an MB to see how much sludge was left from convential draining and compared it with a Topsider type unit sucking it out. IIRC there was little difference between the two.
As has been stated here before, there is no sump plug on inboard boat engines and they survive.
One certain advantage is that the sump plug does not get mangled, overtightened or cross threaded which you might discover 6000 miles or more later.

A quote from one forum member
Mercedes engines have been designed to have their oil sucked out through the dipstick tube since the 80s. If you drain the oil by pulling the oil pan drain plug, you definitely will get less oil out than when using the Topsider. I did a test almost 5 years ago to prove it to myself.

Whatever method used there will always be some negligible quantities of old oil left. It doesn't matter.
