Best oil for a sitting vehicle?

[Doug Hillary]

Hi,
Thisisrandy - If this is a continuing situation I recommend you use a lubricant of the correct viscosity that has a Vapour Phase Inhibitor (VPI). These protect against rusting and cam corrosion in little used engines

You'll need to use a quality fuel stabilizer ALWAYS. And, if you do use the truck, run it 'til its empty refill w/stabilizer and park in living room... Stabil-Marine or Pri-G at every fill up is a must.

Visit your industrial and/or marine diesel shops. Gensets and marine engines sit often enough and usually get a quart of VCI oil.

Toyota full synthetic 0w20 has a ton of moly. Its an easy choice for your yearly OCIs. And, you still have to change the oil based on time for that warranty.

I like the last 2 comments. Personally? I have gone over to AMSOIL Signature Series for a yearly OCI on my Dodge Stratus(125k miles currently) and it sees about 3-4k miles a year MAX.

This is my first run with this setup and I have added some LubroMoly MoS2 to try to curb increased wear due to long periods of the car sitting. Especially if/when gas prices go through the roof.

If any negative numbers show up as a result of the LM, I may drop using that and the AMSOIL Signature Series is probably enough in of itself.

PS: I wouldn't use an additive to the oil unless there is a specific problem, such as moisture, on a often parked vehicle. If I were doing longer mileage intervals I wouldn't have used the LM product in the Stratus anyway, as this probably hurts the oil's formulation in the long run for extended OCI. I feel comfortable using it under 3k miles, though a year in service. Will be performing UOA at 6 or 7 months.

and it eliminates the need for even a 10w30. Ivve agonized over this much.

Why is this perfect? If it is ester based, than it's hygroscopic and will accumulate moisture.

Interesting. I've never heard of this and googled for it.

There was a study military did on this:

Quote:
Engine oil meeting specification MIL-L-21260 provided satisfactory protection during the 3-year storage test. The experimental VCI oil also provided satisfactory storage protection during this test; however, there was no observable advantage for the VCI oil.

Randy,

How about planning a road trip every couple of weeks to keep the Tundra exercised? It's not enough to just think about putting a different oil in the crankcase, but also about transmission fluid and diff lube. Do you really want to get into changing all of those, too? Since you like the truck, make a point of taking it out and driving for at least an hour on the highway every couple of weeks. Then you'll get the enjoyment of driving it, and the truck will get up to operating temperature to keep everything lubricated.

Hi,
friendly_jacek - The MIL-21260 Spec is for a special lubricant and they are not readily available!

Lubricants with a VPI are widely used in the Commercial world and available at Agriculture supply shops - usually in a 15w40 viscosity with a API C?/S? Quality rating

Doug,
Thanks for the info. I learned something new. It would be cool to use one of those VPI oils as fogging oil for my boat that sees little use.
