Since your drive to work is really short I suggest using a good synthetic and maybe even a euro 0w-40 and I'll tell you my reasoning why.
A 0w-40 will be a bit better when the inevitable fuel dilution comes into play and its ideal for cold starts. I'd then move to a yearly change, likely in the fall so the oil is new for winter.
Then I'd plan on a bi-weekly highway run of about 30 miles at steady cruise to evaporate any accumulated fuel and condensation.
I think you'd be ahead simply because you'll only be changing the oil yearly. And m1 0w-40 is only 26 bucks at Walmart. So basically 30 bucks a year for oil and filter.
Be sure to find a euro long life oil though. It will say it on the back. This would be what I'd do.
That's an interesting idea. I hadn't thought about a 0w-40 but that would seem to cover all the bases. To be honest, running a full syn in an engine this old concerns me though. The engine does have a thin layer of black sludge (a coating but nothing like thick pudding to be worried about) visible through the oil fill hole and I'm willing to bet that some of my gaskets and seals are still holding oil in due to some sludge retention. I'd rather not stir the pot and cause leaks with a synthetic from seals that currently aren't leaking in the first place.
That being said, Mobil makes M1 0w-40 High Mileage, no? With seal swellers to counteract my fears that might be the hot ticket. Interesting and thought provoking idea, thank you Clevy.
K. No the 0w-40 doesn't come in a high mileage flavour however if you are concerned about gaskets I suggest buying a product made by a company called liqui-moly. It's called motor oil saver. The stuff is amazing at stopping leaks,unless the gasket is physically broken.
You can find it at napa for 7 bucks a can. It will also raise the TBN of the oil which will insure that a yearly interval is no problem.
Motor oil saver will condition your gaskets and stop any potential leaks before they start.
So with the extra 7 bucks for motor oil saver that brings your yearly expenditure up to less than 40 bucks.
Because you've mentioned there may be deposits in the engine I suggest using a really good extended drain filter like the fram ultra,or for the first year change the filter at the 6 month mark.
The fram ultra will hold 27 grams of particulate so it should be good for the year.
I'm using the fram ultra for 20000 miles however my engine is known to be clean.
The M1 0w-40 is going to clean stuff up. The motor oil saver is an ester which will also clean stuff as well as condition the gaskets.
Now that you've mentioned deposits I would add a bottle of mmo,or a can of seafoam right away to get a head start on the cleaning and get a lot of the deposits into the existing filter.
Then at oil change time use M1 0w-40 and a can of motor oil saver,along with a fram ultra and start with yearly changes from that point going forward.
