If that 50 miles is pretty much weekly and continuous without the car cooling down much, I'd say you could go with Mobil 1 and do 7500 miles..

Heck, just use dino and change the oil just before the boating trip

You should change the oil in your vehicle at a quarterly interval every

The quarterly interval is bull. When the truck is just sitting there, the oil is not breaking down at any appreciable rate.

Do you have any evidence that there really is good reason to change the oil? As far as I can tell, there is absolutely no need to change the oil every 3 months if you put less than 3000 mi. on it.

It AINT the "sitting there", it's the 1.5 mile commute.

I explained that above.

Actually you should change every three to four months. There is plenty of proof out there. Do a google search. I was surprised my self when a couple of years ago Car and Driver did a review of different oils and how they break down over time. It is not the sitting there that breaks them down but little use is almost as bad as a lot of use, and hard use you should change it more often.

It's my 3-rd lease. They don't care how often you change oil. They simply auction the car at the lease end and nobody owes anyone anything. There is no need to present any maintanance records. But anyway, I would like to keep the engine in good condition, despite that I am only going to use it for 3 years. Changing oil is not a big deal. Takes only few minutes. I just thought that I can use synthetic, as they say it's good for

Who makes the claim? Who's they?

According to Mobil1

I think there are a lot of mechanics who really believe you have to change oil at 3k mi. I don't agree with them (although I do agree changing your oil often enough and using good, quality oil is very important). Of course, what often enough means is the question.

Personally, I use synthetic and change it every 5 k mi or so.

Virtually every new car here in South Africa has oil change intervals of either 15000km (9375mi) or 20000km (12500mi) minimum, and I think one or two makes may even have 30000km (18750mi) intervals (possibly on synthetic oil).

I'm unusual in that I like to change my oil every 7500km (4700mi).

How long do cars usually last out there? Do you think there is any difference?
