Hi again, gang. Time for another oil change soon, which, as usual, raises new questions in my mind.
Some of you may remember that I drive very little, since I usually choose to walk the short distance to work everyday. So there are some weeks, I may not start my lovely and lovable '06 silver Camry LE for
3 or more days. Shucks, one week this past summer, I didn't drive it anywhere or start the engine for 6 or 7 days.This leads to a question about rust protection.
I found the following Q-and-A on the Mobil1.com web site:
Question:
Protecting An Infrequently Used Engine
"I use my Porsche infrequently. Will Mobil 1 drain away from the parts more quickly and therefore potentially leave them "dry" when I re- start the engine. Is there anything I can do to minimize this problem?
-- Mike Hughes, Felixstowe
Mobil 1's Answer:
Any motor oil is going to drain off the internal components of your engine when it is shut off. It is not likely that the components will be completely dry, but after an extended time the amount of oil residue may not provide the necessary protection to avoid rusting and also may not provide enough lubricity for start-up.
### [Well, this applies to my Camry's situation, and I don't want my sweet little Camry's engine to begin rusting by only starting it once every
3 or 4 days. The answer above does not say how long "extended time" is.] ###The answer continues:
Mobil 1 will provide maximum protection and will flow much more quickly than conventional oil to all the engine components when the engine is started.
### [This is certainly true, but my guess is that conventional oil might leave more of a residue (and thus provide more rust protection) to the engine's parts during a 3 or 4-day no-starting lay-over? As much as I love synthetic, I'm concerned it doesn't "stick" to engine parts over
3 or 4 days as well as dino oil.] ###Mobil 1's answer ends:
We suggest you review with your Porsche dealer how often you should start and drive your vehicle to assure good protection for your vehicle's lubricated components.
