Engine Oil top ups (thing of the past maybe?)
Just chatting with a neighbour about engine oils (as you do) and
remembering how, after an oil change, a sticker would be put on your engine to show what oil had been used. It used to be helpful back then - I would think even more now with synthetics, semi-synthetics and mineral oils in use. Has anyone seen this recently? |

Many makers these days specify the brand and type of oil to be used exclusively. Last time mine was serviced, they included a top up pack of the correct oil - a litre in a plastic bag with disposable gloves and tissues. ;-) -- *The severity of the itch is proportional to the reach * Dave Plowman London SW To e-mail, change noise into sound. |

I was told that with new cars main agents are obliged to put in whatever is in the manual or originally in the car. Wether you believe that is up for discussion, I a friend who had a particular fondness for Triumph Dolomites in the day and had a battle with his local Lookers BL garage who charged by the quart can for oil despite being told by a mechanic that the oil came out of big drum at the back of the garage.

Richard , Dealers today still buy oil in bulk. But charge you the retail price per litre. Had my car serviced by the local main BMW dealer (spit) now thankfully closed down. I picked it up from them and looked under the bonnet to check they'd fixed a leak from the steering - which I'd asked to be done and been charged for. If they had, they'd not cleaned it up. So checked the oil too. Well under full on the dipstick. On their level forecourt. I'd not even started it. Workshop manager said this was impossible as their equipment measured out the correct amount for each model. And told me I didn't know how to check the oil. So got the c**t to show me where I'd gone wrong. Even gave him a tissue from the box in the car. He obviously loved looking the fool he was. Then told me I should have asked to have the leak from the steering cleaned. I hope he lost his job when they closed down. -- *It's a thankless job, but I've got a lot of Karma to burn off Dave Plowman London SW To e-mail, change noise into sound. |

Richard , All garages used to to that in the days when most cars used the same type of oil. Local Citroen /peugeot dealer had oil pipes delivering from a bulk tank round the back, to individual nozzle guns at each of the 4-post ramps, 6 of them I seem to recollect. Now almost every model seems to have its own special oil code. These days they all seems to be running the 'oil flush treatment' racket, where this wording is printed on the invoice and billed at anything from 9.99 to 17.99 plus VAT. |

We have a 7-yr-old Panda Eco (does a fantastic job as "the shopping
trolley"). In the recent (and ongoing) unpleasantness it was due a service, but our garage had shut up shop. I suddenly realised that _this_ was _one_ thing I could DIY on a car these days. Long story short: I looked at the 3 or 4 part-full oil bottles I had had in the garage for umpteen years, and they came, together, to about a litre less than I needed (of 10/40 oil). So I went to our (magnificent) local motor factors and reviewed the litre bottles that they had. Cheapest was a synthetic oil. I asked the lad there (an about-40 yrs old lad, spent all his working life in the motor factors, and engines) about mixing this with the oil I'd got: he said "doesn't matter - just shove it in, as long as it's the right viscosity". So I did. The Panda hasn't complained yet. (It does about 4000m per year btw). My 2p John |

But might well cause premature engine wear. Oddly, it can be more so on older engines. Pushrod engines have much higher loads to the camshaft than modern OHC multi valve types. And a worn cam may not stop it running, but will reduce the performance and increase fuel usage. -- *Stable Relationships Are For Horses. Dave Plowman London SW To e-mail, change noise into sound. |

Most modern engines are 120-180k before there is *any* noticeable wear. Metals are harder, oils are better and machining is to far tighter tolerances. My 2008 Peugeot has done 180,000 and it's still on its original clutch (*), exhaust system and shock absorbers. The timing belt was replaced at about 100,000 miles - not because it was worn but because this was the mileage stated by the manufacturer, and a broken belt would cause a valve/piston collision and hence major engine repair. The water pump was replaced at the same time simply because it is driven by the timing belt and the labour to replace the pump is the same as to replace the belt, so it makes sense to replace the pump just in case, rather than pay for a second lot of labour some time later on (the cost of a new pump is a lot less than the labour to replace it). OK, so it's needed a new catalytic converter and diesel particulate filter, two things that a 1960s BMC A or B engine would not have had, but those are there for environmental rather than performance reasons: the car would run (illegally) perfectly well without them. I'm not aware of any rust on the body or on any of the structural members. My first car, a 1980 Renault 5, suffered from bad rust over the rear wheels, but even that wasn't structural. (*) Although the bite point has gradually risen, there's no hint of slippage so it doesn't need replacing yet. I've never had a car before that has lasted beyond about 80,000 on the same clutch. |

I still find it mildly astonishing that you can still see through the oil in my Jazz after a year. Well the darkening is (mainly) soot from the combustion bypassing the rings, so I am guessing they've improved the tolerances ? More likely I think improvements in combustion technology from a combination of injection, sensors, and ECUs, leading to much less soot. The soot was as much as anything oil exposed to high temperature blowby gases. The fact of the matter is that materials have come on hugely. A 1960s BMC A or B engine needed new big end shells at 30,000 and mains at 60,000 or a complete rebuild with rebore and new pistons at 90,000. Anywhere near the coast in the western or southern parts of the country and they rusted away long before they needed major engine repairs. In the 60' and 70's people actually made a point of buying 2nd hand cars of the more up-market models that had only been driven in places like east anglia Most modern engines are 120-180k before there is *any* noticeable wear. Metals are harder, oils are better and machining is to far tighter tolerances. |
