Don't like the time between oil changes

When it suits me, I am British. When it doesn't, I am not ;-)

Hardly anyone bothers with cars. They just change as indicated in the owners manual. As you say, the oil in many diesel engines gets jet black with dirt within minutes [no exaggeration] of changing for fresh oil. This is quite normal and doesn't stop diesel engines living a long and productive service life.

Even my old indirect injection land rover diesel engine lasted over 22 years until last night when it finally expired with a bang. Its oil always had a filthy dirty appearance yet it lasted over 12,000 operating hours which amounted to 140,000 miles of short journies, many towing up to an illegal five tons [allegedly;-)] while carrying a ton payload. Not bad for a 67hp

2.5 old technology engine revved to the governor routinely.

The USA has been slow to embrace diesel power compared to Europe. In fact, for several years the emission standards for diesels were such that no diesel powered new cars subject to emission testing were available from US or European manufacturers. Within the past couple of years new models that meet the emission requirements have become available. I became a believer when I purchased my first diesel powered boat and now drive a diesel pickup truck as my daily driver. Ultra-low sulfur content (15 ppm) diesel fuel became mandated here in Oct (replacing the low-sulfur fuel of 500 pmm). It definitely burns cleaner and I've noticed that the occasional "whiff" of diesel exhaust smell has completely disappeared.

Yes they have removed the aromatic compounds as well as sulphur. A by-product of reducing sulphur is, as you say, less soot through the exhaust and combined with direct injection engines, less soot in the oil as well. This is partly the reason that some European diesel engines can run far longer between oil changes than petrol engines from the same manufacturer. For instance, some VW and GM diesels can go for up to 30,000 miles between oil changes. Yes, its worth repeating for those that change their oil every

3000 miles, 30,000 [thirty thousand] miles between oil changes.

This garage in downtown Manhattan advertises oil and filter change for $70.00. This guy takes his car there 8:30 am sharp for the special and picks it up later in the afternoon. He does it day after day after day. A few days later the garage owner tells him, "Sir, I note that you have had the oil and filter changed in your car for 12 days in a row, you don't really need it this often".

"Yeah, but it so much cheaper than parking in downtown for the day" replies the guy:-)

Thought it was time for some levity:-)

Reminiscent of the story of the rich businessman going to see his bank manager on the edge of town and asking for a loan of 2000 dollars for a fortnight.

The banker is puzzled but readily agrees.

At the end of the fortnight the bank manager can't resist asking why, since the businessman did not seem to need the money.

Businessman: "I was allowed to leave my car in your car park."

Banker: "Yeeees."

"How much interest are you charging me?"

"About 8 dollars at 10%"

"Exactly. A lot cheaper than parking at the airport down the road while I was away on holiday."

I find it interesting that you PAY EXTRA for an engineering team to figure out stuff like the optimal interval between oil changes, then ignore their advice. The factory honors warranty claims made where the intervals are observed, therefore logic says the intervals are proper -- indeed, I'd maintain that the intervals are short if the factory says they will support the warranty if they are observed.

You should understand a couple of things, among them the fact that oil technology has come a long way baby. If you read the owner's manual, you would find that the intervals are calculated based on the kind of driving the car is put to. If you are into lots of short trips, the interval is shorter, if you drive long distances on the freeway, the intervals are stretched.

I see no need to attempt to second guess people that get paid 6-figure incomes to figure out the optimal usage that the oil can be put to.
