I know you know this, but I can't help but mention...

Long distance miles vs. city miles are different due to heat/cool cycles, etc., though... I'm sure your 10k miles will show cleaner oil than mine will (500 miles/month). I'll probably change mine at 3k or 5k just to be safe. Whether I do it myself will depend on when Birmingham opens up and if I really want to drive 3 hours for an oil change. I'll probably do it myself after seeing some DIYer success.

418 miles... nice job.


Incidentally, does full synthetic like Mobil 1 need changing after a year even if it's only been driven 1k miles in that time?

Mine to.
I know of engines I've built that have over 400 000kms on them and they are still servicable.
Not including diesels of course. I've done a number of Toyota B's and 3B's that have double that.
How long do the motors you build last?

Thanks. I think you're right about city vs country miles. I'm probably not putting much strain on my engine.

As for the synthetic oil, by hunch is that you do have to change I'd after a year since it breaks down over both time and use. But I'm no expert.

No, Mobil 1 does not need fo be changed after a year with low or high miles, unless you put over 20K miles on it!

Question:
Are More Frequent Oil Changes Required in Humid Locations?
On a previous question regarding the possible need to change Mobil 1 Extended Performance more frequently based on driving conditions, you referenced the results of the Las Vegas taxi test, which suggest more frequent changes would not necessarily be required. Las Vegas is an extremely low humidity climate. If I drive only 6 miles a day, taking a longer trip of 200 miles once a month (no towing) and I live in a climate where humidity is routinely greater than 60%, is there a need to change the oil more often than the prescribed 15,000 miles or annually which ever comes first? Your guidance is appreciated.

Answer:
Under the circumstances you described, Mobil 1 Extended Performance will still provide the outstanding protection of the Mobil 1 family of products. You can keep changing the oil every 15,000 miles or once a year.

Question:
Can a BMW Go 19,000 Miles Between Oil Changes?
What about a really long drain period? My 2006 BMW 325 has gone 16,000 miles since the last oil change. I added a quart of Mobil 1 about 2 months ago. The vehicle's service computer is indicating the next oil change is not due for another 3,000 miles.

Answer:
When your car is under warranty, always follow the owner’s manual or in this case, the oil sensor monitor for oil change intervals. We are glad to hear Mobil 1 has gone the distance for you.

In the case of the smart fortwo, either once a year or 10K miles, whichever comes first. More often in severe duty use.

Interesting. I guess Mobil 1 is officially as good as people claim it is. I remember doing a lot of online (google) research to decide whether to switch the SUV to Mobil 1 and 6000 mile changes, when it had dino oil for its first 45,000 miles. I switched and noticed an immediate improvement that I never saw with a fresh Castrol 5/30 oil change; even 10,000 miles later (changed again after 6k) it seems to pull better and sounds smoother on hard acceleration. Could be placebo effect, but I'm sticking with Mobil 1.

I read somewhere that full synthetic oil, especially Mobil 1, will actually stick to the metal for about two days and is the best choice to prevent wear on the first start of the day. I only found one nonauthoritative reference to that, though.

"Severe duty use" includes numerous cold starts and short trips at too short of duration at operating temperature to evaporate and rid the oiling system of atmospheric condensation. Has nothing to do with fossil oil or synthetic oil; under those conditions the condensation accumulation is a constant for either.
