engine oil

have started to do a bit of servicing on my old bx diesel......i suspect that the oil hasn't been changed as it should because of 'suspect' servicing by someone else who should have done a good job...
drained all the old stuff out....new filter and 5w30 synthetic oil.........the intention is for it to act as a good flushing agent for a while....but don't know if i should just keep using it.......after all, synthetic oil has better load characteristics and is cleaner......any opinions?

Depends what you can afford. You might also trial synth vs mineral oil on the same change intervals to see which brought out more suspended dirt when you dropped it.

i get my engine oil 'out of the back door' multi-fleet 5w30 synthetic for vauxhall vans, however i've just spent nearly 20 quid on semi synthetic 15w40 just in case.....

i remember not so long ago when i checked my oil when i got it home from a service and it looked quite black.......my man said that new oil goes black very quickly in a diesel..........however ....have checked my new oil after a few miles and i can still see transparency......with black staining in suspension....

Oil in diesels does change colour very quickly.

But usually it takes a little longer than the drive home from a service.

I hope they gave the oil filter a little polish too

So are you saying you nick your oil from your employer but object to being ripped off yourself?

I use Comma semi synthetic in all my cars, costs about £13.00 from Trago Mills, use the cheapest oil you can find that is within spec and change it every 5,000 miles, your engine should last almost forever then.

I have just changed oil in my C5 that I bought from main stealer, Total Quartz 9000 £29 that I thought was pretty good. However Sportif, Aylesbury are a bunch of pompous dickheads as the managed to also sell me incorrect filter £18 and wrong sized copper washer 99p.
First time changed oil in this car so I didn't see the difference until I went about it, so being a Sunday I had to hellfrauds to get correct ones.
I am going to give them some stick at Sportif tomorrow.

PS: Sportif at Chalfont Saint Giles are superb another 12 miles for me tho.

On my Xantia TD I go for the cheapest 15W/40 oil in spec from the likes of Asda, Aldi or Lidl and change it and the filter every 4-5k miles. I got a bulk deal on filters - Purflux 1109's 10 for £12. Never had any problems and it uses no oil between changes (roughly every 4 months) I like new oil in for the Turbo mainly. Mine turns black within a hundred miles or so. I put it down to the residual oil still in the engine plus the usual diesel soot. Friend of mine just back with Ford Torneo - oil & filter "service" at the Ford Stealer - how much? £179!!! Told him about my £12.99 oil & £2 filter! - sick is not the word!! I can do my change in 10 minutes! Back from a run - select high. Switch of engine - take off cap - remove plug - let oil drain into receptacle. Whip off filter. While oil dripping out - fill filter with fresh oil. Refit plug. Finger over filter opening - spin on new filter. Refill to just under max mark. Done

perhaps ...'out of the back door' was the wrong term........more of a perk.......always something left at the bottom of the barrel......
