Oil service in West Chester

The right oil is an approval, not a weight

The cap says 0W-20 or 5W-30. That is the oil's thickness, and it is the least of it. European makers test oils one by one and publish a list of the ones they approve for each engine — BMW Longlife, Mercedes-Benz 229, VW 502 to 509, Porsche A40 and C30. The approval is what protects the timing chain, the turbocharger and the emissions equipment over the long drain intervals these engines run.

So we fill by the approval:

• BMW and MINI — Castrol EDGE approved to BMW Longlife-01, Longlife-04 or Longlife-17 FE+, whichever the engine calls for.
• Mercedes-Benz — Castrol EDGE approved to MB 229.5, 229.51, 229.52 or 229.71.
• Volkswagen and Audi — Castrol EDGE approved to VW 502 00, 504 00 / 507 00 or 508 00 / 509 00.
• Porsche — Castrol EDGE approved to Porsche A40, C30 or C20.
• Jaguar and Land Rover — an oil approved to the Jaguar Land Rover specification your engine names.
• Volvo — an oil approved to Volvo's own specification for the newer engines.
• Domestic and Asian cars — Castrol full synthetic in the grade on the cap: an oil carrying GM's dexos license for a GM, an API-certified oil for the rest.

If the oil your engine is approved for is not on our shelf, we order it. We do not substitute something close.

What an oil service includes

• The old oil out, and the approved oil in to the right level.
• A new filter with its seals.
• The service reminder reset.
• A bumper-to-bumper inspection — the road test, under the hood and under the car — at no charge. You get the findings on your phone.

How often

We recommend an oil service every 5,000 miles, and every 3,000 once the car has passed 100,000.

That is shorter than the 10,000 miles on many maintenance schedules, and on purpose. The maker's interval is the longest the oil can go under good conditions. Short trips, stop-and-go traffic and turbocharger heat are not good conditions: the oil thins with fuel and loads up with soot, and the parts that pay for it — timing chains, their tensioners, the turbocharger — cost far more than the oil changes saved.

Wait or drop off

An oil service fits one of our four waiting appointments a day: 9:30, 12:00, 3:00 or 4:30. With the inspection, plan on about two hours for a European car and a little less for others. Or drop the car off and we will text you when it is ready.

The rest of the schedule

While the car is here we check what else is due by miles or by age: brake fluid, coolant, spark plugs, the engine and cabin air filters, and the fluids that are easy to forget — transmission, differentials and transfer case. If the car is new to us, bring its records; we do not quote work that was done last year.

Oil service questions

How long does an oil service take?

About two hours for a European car on a waiting appointment, inspection included; a little less for others.

Does my European car really need a special oil?

It needs an approved one. Two oils of the same weight can differ in exactly the things your engine depends on — how they hold up to heat, how much ash they leave in a particulate filter, how they protect a timing chain. The maker's approval is the proof an oil was tested for that engine.

Do you reset the service light?

Yes, as part of every oil service.

My car says 10,000 miles between services. Why change it sooner?

Because that figure assumes ideal use. For the short trips and traffic most cars around West Chester see, 5,000 miles keeps the oil doing its job and costs far less than the timing chain or turbocharger that worn-out oil wears down.
