The new Tundra I have only spec’s doing oil changes with Synthetic every 10k...

For the First 10k I personally changed it at 3.5k, and 7k miles just as a precaution, now I’m thinking go to 5k miles per oil change for the next 10k...

But 10k between changes ? That’s a LONG time.

thoughts ?

Im one of those that changes oil and filter every 5K even though my manual says 10K I prefer my oil to be carmel colored not black!

I used to do anywhere from 3500 to 5000 mile oil changes on older vehicle until my 2013 tundra. It came with synthetic oil and recommended 10k changes - I drove it for 150k, 10k oil changes, sold it to my cousin last fall, it's still going strong, runs great, doesn't use any oil. My 2020 tundra I plan on pretty much the same.

I guess if you tow a lot or otherwise work the engine harder than "normal" shorter intervals might still make sense.

Unless you are doing a LOT of towing or a LOT of dusty roads, 10k miles is nothing for synthetic. The last two Land Cruisers I have had were bought new and I changed oil at 14-15k intervals... It still looked good and had no smell. First truck was sold at 342,000 miles with no problems and the last one has 363,000 with no problems. Your results may vary.

Dirt roads make up 5% of my driving and I tow nothing more than a john boat or a Polaris...

I have a 2008 4runner that has 250K miles on it. 10K between changes using Mobil 1 with new oil filter/ air filter and drive train greasing with Mystic high temp red grease. No issues.

My RAM diesel says every 15,000, but I stick to 10,000

I also have a Ram diesel. I typically drive from 7500 to maybe 9000 miles a year so I just change it annually.

I changed my 07 tacoma every 10k w/ mobile1 when the manual required 5k intervals.

When the pickup was wrecked at 211k, I had just done an oil change, and when I checked the level prior to changing it it was right where it should be in the dipstick. Don’t use any oil that was detectable, just as expected

I also changed the tacoma (and now Tundra) at 1000-1500 for the first oil change.

I’m not convinced you will get any more life with 5k changes. Not that 211k is a lot, I think Seafire has a 22r with way over 500k on longer than 10k changes.

even though it's a PIA.......I'd at least change the filter @ 5K

Now the '06 Tacoma.......I know I would change the filter @ 5K

I like clean oil

Having been involved in fleet maintenance during my career, I'd remark on a couple things. Using the science of oil sampling, A filter does not clean the oil, it is only a suspended particulate trap.
Oil's life is determined by acid/ph balance, corrosive chemicals suspended in the oil created by condensation, cold starts and oxidation, and silicates from intake air (dust). Never change an air filter because it makes you feel virtuous. More silicates are introduced into the engine during filter changes than any other time. A typical highway service paper pleated, impregnated air filter doesn't begin to reach peak filtration until the 'filter minder' shows about 1/3rd restriction. SI engines (gasoline) usually are well within limits on oil contamination at 15 or 20,000 miles. Diesel engines can go much longer, almost indefinitely, when subjected to routine sampling. Eventually, diesel particulate load becomes a problem, and the oil needs to be changed, or in the case of industrial/marine units the oil will be centrifuged to reduce particulates in suspension. Most diesel fleets now are using fuel consumption formulae to determine oil changes after setting the standard with sampling. We overdo it to a ridiculous degree. But, this is not to start an argument, I'm merely pointing out what the industry standard is...you do what makes you happy.


Well this is a fine pickle we're in, should'a listened to Joe McCarthy and George Orwell I guess.

10,000 mile with synthetic oil shouldn’t be an issue as long as the crankcase is kept full.

2002 tundra 4.7L almost due for its annual 10k oil change at 190,000. Mobil 1 synthetic, and unbelievably the oil still looks almost new.
Last winter tore down a 4.7 with 115,000+ miles and it was unbelievably clean, no sludge at all.

my tacoma every 6 months or 5k with synthetic oil is cheap insurance

I'm pretty much a hard core old timer. I did switch to 5K changes on my 2004 Tacoma and when I had Dodge Diesel I went 1 a year and I typically put about 6K on it every year.

Now I have a 2019 Chevy Duramax with one of those computer oil life read outs on the LCD screen. It reads about 18% left when I have about 3K miles on it. I bought the 100K extended warranty on it when I bought the truck new as the cost was about the same as one injector pump and I had put 3 of them on my Dodge.
So the oil change is free for me.

I have never known too frequent oil changes to be detrimental to an engine,but dirty oil sure can be.I do a lot of driving on dirt roads an over 50 % of the driving is towing/hauling heavy loads

I have an Equinox with the 2.4 four cylinder. I change that cars oil every 3500 miles or once a year with dexos rated synthetic. My gasoline truck is a 2003 and I change that oil every 4000 miles with Mobil 1. I think 10,000 is too far if you use your truck to tow or live in dusty conditions way out on gravel roads like I do.

"10,000 mile oil change interval" written by the same company that wants to sell you another new vehicle.
My oil catch pan is an old white refrigerator vegetable crisper pan and the difference in the black sludge from my 3,000 mile old oil to my daughter's 5,000 mile old oil was significant. A product of combustion is carbon and that is harder than engine parts, so I suppose that I'm "wasting money" to get rid of the dirt by buying new oil and filters according to the manual. The only wear that I've ever seen on my vehicles is on the drain plug.


My other auto is a .45

There's only one way to know. Everything else is speculation.

I have a 2005 F150 5.4 that I bought new. It has 234K miles and is still going strong. I change oil with Amsoil every 10K. I sent samples into Blackstone the first 8 oil changes. Always came back perfect- so I quit sending samples. Haven’t had one problem. 10K should be a breeze.

15K intervals with Mobil One full synthetic with Mobil One filters here. Extensive research lead me to that decision. And that research mirrors what flintlocke posted. Toyota doesn’t want to sell you a new truck nearly as bad as they want your truck in the maintenance bay at their dealership every 2-3 months.

As mentioned, everything is just a guess unless you're doing used oil analysis' after every change. It's a small price to pay to know exactly how your oil is performing. Amsoil is what I use and is superb.


It is irrelevant what you think. What matters is the TRUTH.
