10,000 Miles and Counting on Mobil 1 and Mobil 1 Oil Filter on 2007 Escalade...

[CTS-V-TWIN]

I just wanted to report that the last time we changed the oil in our 2007 Escalade was back on August 30, 2007 and since then, we have clocked 10,000 miles on Mobil 1 5W30 Truck & SUV Formula teamed up with Mobil 1's Extended Performance Oil Filter.

I check the oil condition and level every thousand miles and the oil is dark (Mobil 1 is natually darker than conventional oils out of the bottle), but nowhere near black. The engine hasn't consumed any oil in 10,000 miles, so that is a great sign.

The oil life monitor has already cycled through one time and I reset it so I wouldn't have to keep looking at the "change engine oil soon" message and it is now down to 79% oil life remaining.

I have to say that I am very surprised because I have heard that Mobil 1 combined with a Mobil 1 oil filter will go 10,000 to 15,000 miles before needing to be changed, but I have never experienced it firsthand. It is cheap insurance to run Mobil 1 with the Mobil 1 oil filter and you don't have to change it out that often.

I don't know when I am going to change it, but I will keep checking the condition of the oil every thousand miles or so. Once it is black, I will know it's time. I guess the Mobil 1 oil filter does a great job of filtering.

I just got my new Amsoil shipment, their new sig oil is good for 35k between changes , I will go to once a year but no longer.

I would never go that long without changing the oil. 15K is probably the most I would go. Besides Amsoil oil and filters are way too expensive for me to spend on a leased vehicle. If I owned my vehicles, I would switch over to Amsoil in a second. I have about 6 months left on my 2007 Escalade lease before I order a 2009 Escalade.

Thanks for the info Carl! You are hands down the best!

You're right about Mobile 1 going 10k. I have my oil tested when it's changed. It only costs $20 and the report will tell you how your oil is holding up and more importantly how your internal engine wear is going compared to other same engines in their data base. http://www.blackstone-labs.com/ These oil analysis histories helped me sell my previous truck quickly. It's hard to know what to make of an 8 year old engine beyond a compression check but with the oil analysis histories you can prove how well you have maintained it.

Great info! Thank you. How long did you go with Mobil 1 before you had to change it? Better question is what did the labs say the best mileage interval to change the oil out at based on their analysis? What oil filter did you use? I am having great results with the Mobil 1 oil, but only when using it with a Mobil 1 oil filter that is specifically designed for longer service intervals in mind.

I went 9k on my last mobile 1 oil change, SG. I don't know what brand filter the quicklube place installed but I'll be checking that next time. The last time I changed oil was in an F150 with 160k on it with moderate use and occasional towing. The lube place didn't want to top me off when I went in at 6k, tried to push me for an oil change. I told them that mobile one would go 10k. They didn't believe it till I should them the previous oil analysis report. Then they added my free quart of Mobile 1. I don't fit their business model, too bad. I don't fit credit card companies business models either.

The test report won't tell you how long you can go but it will tell you how well your oil and engine internals are doing at the time of the change. See sample report which shows engine wear analysis based on the various metals found in the oil (top section) and oil analysis based on viscosity, flashpoint, insolubles, etc. (bottom section) http://www.blackstone-labs.com/eng_balloon_report_.html.

I haven't had my first EXT oil change yet but plan to around 10k.

I sell a ton of 55 gallon drums of Amsoil to a trucking company that runs the oil thru two of the largest oil filters I have ever seen on trucks, they get their oil analyzed every month, they run the oil for well over 50k miles per truck, they claim to be saving thousands on dollars a year on oil and engine rebuilds.

You change the oil on lease cars/trucks??????

You have to. If something fails and GM can blame it on me for not changing the oil, trust me, they will.

They would not do that, they are your friends.

If Amsoil's claims about 35k change intervals are true then I should be able to do the same thing. Just oil test instead of changing oil automatically. Do the owner's or employees of the trucking company do the same thing with their personal vehicles?

[hcvone]

I know one guy with a 2500HD diesel has a dual filter setup that works there, he runs his oil 25k to 30k depending on the oil results, not sure about others.

[airhammer]

Amazing! I think I'm going to try it. Test at 10k then every 5k thereafter. It still feels wrong though. It was a big step for me to go to 9k. Old habits die hard.

[sj1400]

I recall Audi revising the 10k intervals with the 1.8L turbo engine.. The main reason sludge.. I change mine at 5k using Mobil 1. My concern is the filter even with top of the line filters.

THis is the 1st vehicle I've seen which such long intervals on the oil change monitor - especially with the 07's using regular oil.

[CTS-V-TWIN]

You should be safe against sludge with Mobil 1. I am going to see how long I can stretch the oil change intervals. The oil is still good and the filter should be too. The Mobil 1 oil filter is designed primarily with Mobil 1 oil in mind, so I should be able to really take this oil a long distance. I agree that the 2007 Escalade can go about 8K miles on conventional oil which to me is way too long. The standard GM filter can't filter more than 5K miles anyways. The 2008 Escalades are supposed to be factory fill with Mobil 1, but I checked a 2008 Escalade not too long ago and the oil cap did NOT say Mobil 1 on it and there was no label under the hood that specified Mobil 1 as the factory fill. Is it in the owner's manual?
