Nissan says 2000 mile oil changes

[Fahrvergnügen]

Wow. So, you have resorted to name-calling? Such a professional.

First, I don't care how many companies you've worked for and how long. But since you brought it up, the fact that you have worked for so MANY and NO LONGER do tells me everything I need to know about your "knowledge." It is old-school thinking that needs to die. And you're wrong, euro manufacturers are not the only ones keeping 10,000 mile OCI's. Ford and Nissan off the top of my head based on the owners manuals as well as Toyota.

Go away now.

I am currently working at BMW, so you’re wrong. You are hard headed. All technicians know exactly what I’m saying with the severe service and they too don’t extend oil changes. 5,000 max. Also it says do not follow the oil life monitor in the manual. Also Toyota is a fixed system it isn’t even an oil life system it’s set to trigger at 10,000 miles same as VW. You are not in the business and see nothing we see. We see all these engines here at BMW of people that follow the 15,000 mile intervals. It’s not too smart. Stop being so god **** hardheaded and listen to people that actually work in the dealerships. We share knowledge to protect the consumers of what not to do. Not all techs are trying to **** people. Go to YouTube and watch technician channels, they say the same thing I’m saying, it’s not just a coincidence, stop thinking you know everything about services.

Way back in 1994, my Integra manual said to use 7,500 mile OCI's, except for severe conditions then do 3,750. They defined "severe" conditions as many short trips (<5 miles, or <10 miles below freezing), driving on rough or muddy roads, dusty conditions, extensive idling or low speed driving like deliveries, or towing. I fall into none of those categories. So my old 6K mile or 6 month OCI worked just fine. I only drive it 3K a year now so I just do annual OCI's.

Today’s battle is direct injection and direct injected turbo engines actually dilutes the oil with fuel. It’s the nature of these engines. So the protection falls off once fuel is introduced in to the crankcase. When you start extending these oil changes, you just keep filling it up with fuel to the point all protection is gone and you have a worn out engine.

But since you brought it up, the fact that you have worked for so MANY of them tells me everything I need to know about your "knowledge." I wonder why so many...fired maybe for being an incompetent and/or rude? Left maybe because they all couldn't grasp your "knowledge" level? Either way, your thinking is old-school thinking that needs to die. And you're wrong, euro manufacturers are not the only ones keeping 10,000 mile OCI's.

Go away now.

Also to add I’m 39 years old, so I’m not old school thinking. It’s called seeing and knowing how engines work.

yeah, my wife's CX5 is the first and only GDI engine I've experienced. I had a UOA where they said I could try pushing the OCI to 10K miles, but I have no interest in that. I usually change it anywhere between 6K to 8K miles, using Mazda OEM high-moly 0w-20 oil.

Those lab results don’t tell the full story of oil. That’s smart to not go to 10,000. The skyactiv engines are great, but do suffer from fuel dilution like the others. We recommended 5,000 mile intervals on them too.

So I've had 6 UOA's done on that car, for the last 6 oil changes. Fuel dilution has always shown less than 0.5, and flashpoint always 395 to 405, with OCI's between 6,200 and 8K miles. There was one time I went 8,600 miles, and the flashpoint was down to 375 on that one sample.

It's coming up on 4K miles now since the last change, which the report found possible coolant contamination. I'm planning on having another lab check it, or possibly even both Blackstone and another lab, just to verify that there is actually an issue.

don’t trust blackstone, several members on here say they don’t do a true fuel dilution test it’s only a measure of flashpoint. The potassium they are seeing from ‘coolant’ is in some oils.

Yeah laugh it up mr ford73, I forgot more about cars than you will ever know.

Also, today’s engines have longer, more complex chain drives and DI - be it diesel or gas is naturally “dirty” - more soot load in the oil.

It’s worse in some engines for fuel dilution, like the Honda 1.5T for example.

Nothing wrong with Fahrvergugen working for different dealerships. Techs have to go where the money is. Most techs I know will leave a dealership if work slows down, and move to a faster paced and busier dealership where they can make money. Techs are straight commission.

Cars like the GT-R and Corvette are not your basic drive only to church on Sunday cars. They take a different kind've maintenance than a conservative and practical family hauler. I'd never go 10K on an oil change in something that high end. Like I said in my earlier post, those kid've cars are a different animal altogether.

Starting to feel good about siphoning out oil every 4-5k. Really windy out here in Midwest, but a awesome tailwind rewarded me with almost 42mpg. Pays me back for the money I lost at casino south of Wichita.

I don’t like being stuck to one particular manufacturer. Learn everything about all manufacturers.

I'm sure he meant 2kms oci… a little better right??

Oil never wears out it's a marketing ploy, change the filter every 10,000 miles and just drive.
