How much Oil do you need for an Oil Change?

I believe the Halfords Classic stuff is made by Comma.

 

I`ve used whatever I could get over the years, GTX being a decent buy ..
The key to everything is change it and clean the mesh every year / 3000 miles.....

 

Old-school GTX is 15W40, I recall. Good stuff.

 

Could well be as they're a blender rather than a producer which must keep down costs.

 

I was told 15/40 in a good engine 20/50 if a high mileage engine
VW say both are ok 30 was recommended before muiltigrade was available if you look in a owners handbook for late models they recommend 15/40

 

bit like tea then really?

 

Yes . What can happen, and Comma might well do this, is you buy a base grade of re-processed oil and add the necessary additives to get what you want....you don't do any refining yourself.

 

Wowzer this has turned into a very interesting thread. I have learnt alot.

 

The Twinings of the oil world . I daresay they use reclaimed oil, but no bad thing I think. I'm told it's the additives in oil that break down, rather than the oil itself. If they say it conforms to the relevant spec, it's fine. Nice bit of recycling...

 

Sure is...all our waste lube oil was sold to a re-processor to be cleaned and sold on...not back to us though as the big three had supply contracts. Talking to the rep one time he said absolutley nothing was wasted...the final residue could end up as sewing machine oil or some non specific light oil.

 

So I ended up getting the Halfords one last night.

I believe I have the gasket kit. Fingers crossed I did order it a few months back.

 

Hi dean how you doing. You missed a master class at tekenders mate, I had my engine out and stripped down and rebuilt for the Sunday lol. We changed the main crank shaft and fly wheel seals, this sorted my oil leak out.
Going on the oil change link you have here I used the blue stuff but now use the Halfords classic 20w-50w oil. It really does the job for my standard 1600 mate. Hope this helps and hope to see you at the next tekenders

 

Hey man. Glad to here you got your prob sorted. Couldn't see any 20w50 so went for the Halfords 15w40. Sure it will do the job better than the sae 30.

 

That will do the job, keep it 20w50 and it will hold the heat at a lower rate.

 

I would luv to do techenders. If I can make it, ill fetch rabbit pies!!

 

theres a table in the bentley manual gives all the recommended straight and multigrades for different climate temperatures, the oil should be selected for the lowest temperature for engine starting anticipated
10w/40 is recommended for temperatures down to -20C , 20w/50 is for down to -10C. straight 30 is 0C
VW started recommending multgrades in 1975

 

Another vote for Comma 20/50 as it's described as being for the 'older engine' and is only £10.50 at my local factors. The API is I think the same as the similar Halfords grade.
