They are "technically" correct in their statement, lifetime meaning the extent of time we are required to support the product. Aka warranty and emissions warranty periods for certain areas, the less service required the less they pay and the more they can advertise lower cost of ownership.

Exactly! 10k is "fine" but will not be ideal long term

Done with the octane debate please. I’ll report back after 3 tanks of premium.

Regarding transmission fluid swaps it’s a good idea to do drain and fills, but there are tons of cars out there with 250k miles on them where the fluid hasn’t been touched and the transmissions are still fine. In that case I would leave it alone.

I've been doing 10k oil changes on my F-150 using Mobil 1 full synthetic(except for the most recent change done at a Ford dealer, they use synth blends).

BMW says the transmission fluid is a lifetime fluid in the ZF8. ZF says 60k. I'm going to go with ZF on that one. I'll probably also take it in for an oil change here shortly, it's at about 6k since the last one. Computer is telling me 4k more, but a B58 is going to be a bit more costly to replace than a coyote, so I'll spend the $100 and just get it done. Then I think I'll throw some new plugs in it and get to tuning.

I change my oil every 3-5k.
Only because I'm making amends for all the engines I abused and killed. Lol

Didn't care when I always traded out my cars every 2 or 3 years. Bah, who needs fluid changes. Lol

When I bought my 1994 GS300 in 2002, it had 59k miles on it and the transmission drain and fill had just been performed. When I had the timing belt etc. done at 90k, I asked the shop owner/technician to check the transmission fluid. It was black and after 30k miles, it shouldn’t be. I ended up having a trans drain and fill done at every 8k miles (every other oil change) and then at 177k when it needed a head gasket (not cheap, but the car was heavily cosmetically modified and was worthless with a blown head gasket, so I had it replaced), I had the trans drain and fill done at every oil change. I figured the transmission was the most expensive potential failure item, so I wanted to prevent that from happening. I sold the car in 2015 with 222k on it. The buyer is a pretty well known guy in SoCal car culture. He had 31 cars in his collection including the GS. He eventually sold it and I don’t really know what happened to it after that, but I hope it’s still in nice shape.

None of our three cars get anywhere near 10k miles per year on them, so I have them each changed once a year. Highlander gets driven about 4k per year, Tundra about 7k per year, and GS about 1k per year.

AJT123

Same, we drive nowhere. My spouse is still remote. 6k a year on the MB, maybe 2k the LX and that or less for the LS.

I change the oil yearly on the MB but don’t care about time on my Lexuses.

That's probably where I'm going to end up now that I have 2 vehicles.

If I’m missing 40 torque I’m switching!!


Transmission fluid was never changed in my old Tundra after 230k miles. After 100k I said f it. And I did 10k oil changes in it (once went 15k) and 10k oil changes in Prius (it just hit 151k miles) and it runs just fine. My Tundra next oil change will be after 5k miles because I like to change the oil on nearest 10 thousand number like 30k 40k 50k. Easier for me to remember.

SW17LS

Thats great.

Everybody else, change your transmission fluid and consider doing sooner than 10k oil changes lol

AJT123

That engine is fine for 10k oil changes.

BayeauxLex

You’re saying what could happen and I’m telling you what has happened in my experience and I’m sure a lot others as well…it’s not going to die and it will still perform!!

Margate330

I won't buy a vehicle if I see 10k oil changes on the Carfax, don't want it.

I move on to the next.
