Shipo,
 
I read your common on message 6266 about the low mileage on a VW, I have very simular driving condition about my camry except it is not a turbo. You mentioned need to bring the car to exercise at least once a week, does that also apply to 90F in summer and average above 40 in winter of Alabama weather? My commute to the campus is 100% city stop and go city driving and less than 2 miles, just barely enough to bring the car to normal operating temperature. I just changed my oil to M1 5w-30 which is recommand by Toyota, do I also need to bring my puppy out exercising all year round, and how do I make sure there is no water in my oil? Is it possible to know this just by looking at the exhaust (smoke due to water vapor)? If the answer is yes, can your describe how to do the exercise, is interstate the only way or just drive long enough when there is no smoke coming out from the exhaust? I will change the oil once a year since I drive less than 10000 miles a year,is it a good idea.
 
Thank you in advance for suggestions

My concerns about your driving regimen is that unless you overtly take your car on the road for at least five miles in the summer and more like eight to ten miles in the winter (preferably more), you will accumulate so much water in your oil that even Mobil 1 will start forming acids well before the 1 year mark.
 
As for how to tell if the water has boiled off, there is no indicator per-se (unless your car has an oil temperature gauge, something that very few cars have these days), so it's more of a time/distance guesstimate thing. FWIW, just because the engine is "up to normal operating temperature" doesn't mean that your oil is. Your coolant temperature gauge can easily be showing normal while your oil is barely above 100 degrees.
 
Were I in your shoes, every weekend I'd do at least one ten mile drive so that you effectively purge your oil of water weekly.
 
Best Regards,
Shipo

That is absolutely correct. You might want to look to your states' regulations. CA for example is a (10) % of ethanol: which is (surprise) more costly This of course causes fuel mileage to fall, in addition to the more consumptive nature of operating in winter conditions ANYWAY!!!

Well, yes and no. In many areas of the country the oil companies are required by law to oxygenate their fuels for the winter months, especially in urban areas. That said, some time during the 2006-2007 winter the new EPA regulations for the metropolitan areas of New England (i.e. Hartford, Boston, and Portland) and the surrounding counties were required to convert from good old gasoline to gasoline with a 10% ethanol mix (often referred to E10).
 
The good news (errr, sort of) is that we get the same fuel here year-round. The bad news is that E10 is generally considered to reduce fuel economy from three to five percent. Keep in mind that due to the temperature of the intake charge in the winter time, fuel doesn't atomize as well and your mileage will suffer as a result. Said another way, here in New England, we get a double whammy in the winter time with both cold air and E10 fuel.

Yes, one of the reasons why your states' regulations are important for example is I had read in passing that in the USA, there are a at least 29 separate blends of RUG !!! And we wonder why RUG costs so much!?

I just switched to M1 for my 03 Camry. I read through all the post about synthetic oil is to extend the OCI on milage basis. But in my case, I have owned my Camry since 03, with only 33000 mi (2 mi commute in the morning and 2 mi in the afternoon, and about 1 or 2 vacations a year). That is about 6000 mi a year. So, before my car hit the 5000 mi, 7500 mi, or 10000mi that will take me one year or more. Based on the manual, it recommends to change oil 5000 mi or 6 month (the dealer uses dino), before I reach the milage, the time already pass 6 month. I am pretty confident to run M1 for more than 7500 mi but how about the time factor, stick to 6 month or more?
 
Thanks for any suggestions in advance

I have run Mobil One 5w30 as long as 3 years (I have a 15,000 mile OCI's ) so as you can see, app 5000 miles per year. So 6,000 miles or 12 mo is really not a concern.
 
However if you have 3 years/36,000 mile warranty concerns, you can either ask for warranty fulfillment at the 33,000 to 36,000 miles period or just proceed as you had planned.

Thanks for your help! One more thing, do I need to worry about the water in the oil which shipo mentioned can cause forming of acid?

If you do not change your operating conditions to so called "burn" off the water, using synthetic oil will not change the dynamic. What will change is the increased TBN from 7 (conventional oil) to 12., this means you will have greater acid fighting resistance with the synthetic, but the production of acids will NOT change So let me join with Shipo in highly recommending 30 mins to 60 mins of sustained highway operation to burn that off!!!!!
