Oil filter change in old car - how often?

Unions were the symptom not the ROOT CAUSE. Even the Union man Robinson accurately predicted what would happen to the UK motor industry due to lack of investment. He was so prophetic. The unions continually were banging on about lack of investment hiring management companies to assess the motor industry to get the companies and HMG to take notice. Investment that would create growth and require the workforce to remain.

Thatcher and Reagan were the demise of US & UK industry by not addressing the key issues of investment and moving manufacturing off-shore. Inner-city decay was a peculiar UK & US thing - only because of those two clowns.

Pah, this is all bollocks. I have personal experience of a 100K bike engine that when stripped was well within new tolerances. The oil was changed every 3K - mineral oil.

actually fleet cars doing 50k a year probably have far less wear than the shopping trolley doing 5k..

Castrol ran a series of ads showing the same sort of thing in the '50/60s

- long before synthetic was around.

The point of the article was that they were using a pure synthetic, not crap mineral oils. They have the oil in for 100,000 miles. You have backed them up unknowingly.

It is clear you never read the article.

But that was changing the oil every 3,000 miles. Ford kept the same synthetic oil in for 100,000 miles. Get it?

However they impeded any attempt to invest in machines to make productivity better, even when the market was shrinking because they cost too much.

You made that up.

You Daily Mail reading half-wit it wasn't.

Not for long - he qualified as a plank last week

Ooh - bum fight between drivel and dennis

A gearbox, particularly one in a vehicle built in the past 25 years or so, might not need an EP oil, it might not even need a 'gearbox' oil at all. Times move on, finishing processes are better. tolerances more tightly controlled, debris traps are fitted such that gearbox oil doesn't deteriorate in 4 years. 250,000 miles on a gearbox with a change quality and noise level identical to that when new is possible without any intervention for maintenance. Filling with molybdenum disulphide loaded oil could quite easily leave you with a box that is 'lubricated' but despite that it is totally unusable. Filling with a synthetic oil where it was not originally specified could also lead to problems with the operation of the gearbox leading to more wear. Refilling purely by 'viscosity' rather than a specific specification of oil can also cause corrosion problems.

P.S. It is clear Dribble knows significantly less about oil than he does about hacksaws.

Only if you are a cretin

Time you read up about additives such as ZDDP.

My modern I actually meant 'new' or produced in the last 10 years.

There are times in the past where I have come across a car and thought, that will be a classic, a landmark car. Some of them made it, many didn't. But I find it difficult to think of a single one in the past decade and a bit that even deserves consideration (with the exception of numerous Alfa's and they do it only on looks rather than engineering innovation and excellence)

The oil gets a hard time from the gears-in-the-sump, as on motorcycle engines. Having said that, I've always taken the precaution of changing bike oil at 3K and never had any oil-related troubles. Never used special bike oil either, always a decent car oil of the right viscosity for the bike.

I suspect he was in fixing the bog plumbing.

Maybe not in Germany or Japan, but it was commiting hari-kiri in the UK and the US.

How would it become unusable, drag racers have been using MoS2 for years, with success, with drained gearboxes?

I'm not a fan of high viscocity 'box oil. If I was local delivery or needing 100mph on the motorway every day then yes I'd fit the recommended higher viscocity if summer was approaching. With mostly light driving and the occasional burst of full torque (four seconds in third) the lighter oils work better. Less noise, greater acceleration and no baulking. The escalation of the cost of fuel to the private driver makes the blindfolded approach comical.
