For cars that have the automatic oil change intervals (ie. your example) I am telling customers to use this interval. The PCM is monitoring how this vehicle is driven and it knows when to change the oil. 6-8k on the newer Honda's isn't a problem and in fact my Dad will go over 8k on his oil changes. Most new Toyota products say 5k on their severe oil change.

We work on mainly European vehicles and the German manufacturers recommend extended oil services. We use only the approved oils (MB229.5, VW 505.01, BMW LL, etc.) and do not see problems with the longer intervals. But, the correct oil MUST be used and we double check the service information on every vehicle before we do the oil service. Some other makes use an algorythym in the PCM to calculate oil services, others just use a mileage counter. I believe in following the OEM recommendation, as long as whatever oil is being used meets or exceeds the manufacturer's oil specification. Now, since the vehicle doesn't come in for routine oil changes as often, we are able to perform more thorough services and inspection for the customer (battery tests, tire rotations, etc.) and can place added value to their oil service.

When the typical gas and go customer's vehicle is showing the oil change is "due" comes in, there is no oil showing on the stick, tires are low on air,the engine air and cabin filters are dirty and our state inspection is past due.

What effects are the extended oil change intervals having on cars with clogged EGR, secondary air injection, or crankcase vents. I know at our shop, we see a lot of European vehicles with these problems. BMW's and Volvo's with clogged crankcase vents and oil leaks. Mercedes with clogged EGR tubes. BMW and Mercedes with clogged secondary air injection. Mostly with the Japanese we only see clogged EGR. They don't use the premium synthetics and have shorter change intervals. As an industry, there is something we are missing on the service side. The hard part is selling yet another system service in this age of power steering flush, transmission flush, fuel system flush, intake system service, etc. What problems do you experience with these vehicles and do you attribute any of it to extended oil services?

We seeing quite a few vehicles witgh variable valve timing having problems from lengthy oil change intervals.

 

 

Yes Honda is now have problems with their varable timing controls (Cam Phasers etc) and also timing chain tensioners getting clogged up and causing problems. Now we see them going to 0w20 oil only in full syn grades. I tell our Honda customers 5,000 miles or 15% if they want these cars to out last the bank payments. Cheap insurance for sure.
