http://magnatec.castrol.com/en/oil-range/castrol-magnatec-5w-30-a1.htmlI have a 2006 2.2tdci mondeo, about to do an oil change, I purchased some castrol magnetec 5w30 A5, from asda for £20 for 4 liters thinking I had done good but now not sure I can use it.

The specification States WSS-M2C913-B in the book but the oil I have is the correct weight but is WSS-M2C913-C. Is it compatible?

Castrol site says I should use A1, have I just wasted £40?

Bledd just found it on the site have added a link. Happy now, they don't make it easy do they.
 
That oil meets 913A, 913B, 913C and 913D

So yes its more than fine as 913C is a better performing oil than 913B. 913D is the latest spec.

934B was never a Ford specification, its Low Ash 5w-30 C1 and only ever used by JLR from the PAG days (Ford, JLR and Volvo). It's now obselete and replaced with JLRs own spec JLR ST5005
 
Simon, this is a genuine question, not trolling - what would be the long term effects on an engine if you didn't necessarily use oil meeting all these various manufacturer specifications and instead just used a "good quality" or more generic "{manufacturer}-specific" oil of the correct grade?
 
Good question. 913C has additional requirements over ACEA A5, so you need a better oil to meet the demands of the Ford specification.

A5 alone might be ok, but 913C products will be ok as they are ford approved and relevant to Ford hardware, they also have better fuel economy performance whilst maintaining engine durability. Do you want to take the risk?

In the general context, its very important. More so now with the shift to thinner oils, specs like BMW LL01/ LL04 will have been tested and approved in BMW's engine tests.

Many oils, that you dont see on the marlet, fail these tests as part of development. Its not a case of just running the test and getting a tick in the box. Getting many specifications on one oil has always been a challenge but it's getting more difficult as each OEMs hardware can respond differently

Cheers guys, service done, not sure what oil was used for last service but it's much quieter now.

Personally, no. :) My point was mainly referring to all these people who go to ECP or Halfords and buy "some oil" in the right grade to service their car every year.
 
Yeah they are the same people who say 'my car has no problems with this oil' then they sell it to Vita and the timing chain is knackered.

Its difficult to convince people to look past visc grade and price but it can have a bigger impact later down the life of the car by going cheap.

Ive seen some amazing damage from using an oil that turned out to be not as good as the development guys thought. Cam wear measured in millimetres
 
Sorry i didnt mean to be offensive, just i fail to know how people can state an oil caused no problems. Sure an engine will run on olive oil but people can drive on a flat tyre without noticing a problem.
 
You didn't cause any offence. I was merely clearing the amount of cars that have given me problems.
