Sorry to interrupt folks  but when I put the old oil from the oil change into suitable bottles to dispose of I noticed that is was pretty thick and had lots of quite big lumps of debris in it which considering it was supposed to have been serviced 3k miles ago when we bought it I was surprised to see?? So Is this usual and I have since been told that I should have used a thicker viscosity oil been an older engine with highish mileage, again would this be correct?? Anyway back on topic  I was told I was one of the first from outside of Longbridge to have seen the Metro in production as when I was an apprentice Patternmaker I had to go along with old Charlie the driver to go and pick some things up from there for a job we were doing. I remember having to wait in what I think was the observation room where I could see all the Metro body shells on the conveyer belt way up in the air moving slowly round. Mrs P had a mini and a Metro, the Minis floor had all rotted and was scrapped and the Metro which was given to her by her Dad got nicked and never saw it again  How dirty was the oil on the dipstick before you done the oil change and how clean does it look now after the change ? Bob - In my experience, one of the causes of these globules in oil is moisture. I wonder if there was any moisture in the vessel that Paul drained the oil into? I know that if I drain my oil into a container which is wet there is evidence of this problem when I dispose of the oil at our local Civic Ammienity Site ( Tip! ). Totally agree that the "proof of the pudding" is the appearence of the oil on the dipstick though. Having said that, it won't be as clean as the new oil as there is plenty of residue on the inside of the engine ( enough to colour the oil ) to change it fairly quickly. Anchorman is a great fan of changing the oil in a diesel twice a year to try and keep things clean(er) and provide the best possible care for the engine. If Paul has any doubts about the cleanliness of the engine - despite the "servicing" - should we encourage him to change it again and treat this change as flushing oil? |

I wanted to get an idea if the oil still looks dirty after the oil change as it could be caked up with burnt carbon inside ☹️

I wanted to get an idea if the oil still looks dirty after the oil change as it could be caked up with burnt carbon inside ☹️ Could easily be - If it were my motor I'd change the oil again fairly soon to try and reduce the amount of burnt carbon lurking in the engine. Hopefully the work Paul has already done should get at least some of the carbon back into suspension in the oil. Just a thought :TU: |

Funny you saying that about flushing as my brother said I should have put a cheaper oil in first to sort of give it a flush then put the better oil in.
So If it is caked up with carbon will this cause any damage to the engine, shouldn't the filter have grabbed these rather big lumps, will it be best to run the Rav about for a while first and if I do change the oil again will I need to change the filter again???

I’ve never changed oil into a bright stainless steel pan so never seen the leftovers 😉looking at the dip stick with fresh oil it looks a lovely colour...see how it looks in a few months .
I done a double oil change with my silver Lexus sc430 so that was bit like a flush, just used the same brand of oil as it was only £25 from euro car parts with discount codes found online 👍🏻

From what you said earlier in the thread Paul, I got the impression that you left the oil to drain for a good while - far longer than a garage would. If that is so, you will have got a good deal more oil,and consequently crud, out than a quick oil change would. Was the engine warm when you started?

Yes David the engine was warm and I left it to drain about 24hrs in the end, my mate who used to do the oil changes for me usually leaves his oil drains over night to drain as much out as possible so 24hrs was plenty i'd have thought. :TU: |

Crumbs! - it'll not be used to that sort of treatment if it's been dealer serviced  |

As Andy pointed out recently there is much oil that lays in various ares in the engine so we only ever get a percentage out. So a few drips overnight isn’t going to make any difference.
If an engine is full of crap like that one maybe a top quality flushing oil would be a good idea.

It's like the argument about changing ATF in autoboxes. Some say change it frequently, others claim it can dislodge sediment and damage the innards so only change at the last possible moment per the manufacrurer's service schedule. Where you stand depends on your own experience or who you trust the most.
If I were you I'd change the oil again in 6 months or earlier if you see that the colour of the oil on the dipstick has gone very dark (it will darken a bit over time so don't worry about that). Then go back to annual changes unless another 6-monthly or earlier change is warranted by the oil going black on the dipstick. Always change the filter; they're cheap but do a crucial job.
Bearing in mind the age of the car there can't be too much amiss with the engine if it is otherwise running OK, not making worrying noises or drinking fuel at an alarming rate. Also engines are pretty robust given that they spend their entire working lives knocking hell out of their internals and effectively trying to destroy themselves! Particularly Toyota mills which are generally bullet-proof. Be sensible but don't get paranoid, Paul.  |

Cheers Jim :TU: think I will leave it for six months but keep an eye on the dipstick as you suggest and take it from there, but if I hadn't have drained the oil into the meat tin I wouldn't have seen the bits of debris and wouldn't have thought anything of the oil change nor if it had been done at the dealers or any other garage so just been cautious in case anything was awry :yes: |
