VSOT..........interesting darkening

[Pablo]

Running a full container of VSOT in both my Volvos. The oil appears normal, maybe just a tad darker. What is darker are the metal surfaces. Don't know the real cause - either the thickeners or the Mo or the P....

I'll have to take a peek under the cover. I added a bottle to my refreshed 3.0 ..the oil had a slightly darker tint to it ..but I didn't notice anything else. I guess the stuff is like dark Karo syrup

The oil in both my cars with Amsoil/Pennzoil/LC and VSOT is now extraordinarily DARK.

Not a huge issue.

It does bug me that the metal surfaces in the newer Volvo 850 are darkening way beyond the typical Amsoil golden.

What is the sump size? Why run a full bottle(15oz)?

 

[Brikhead]

VSOT itself is fairly dark in color. Like Gary, I've noticed that it does make new oil a shade darker on the stick(my current mix is 6oz VSOT in 4qts Maxlife dino).

Pablo - What grade/weight oil are you using in your Swedes?

 

[Pablo]

Sump in the new Volvo is about 6.5 qts. Old beater is about 6. (dual remote)

Why not a full bottle?

245Ti has a 15W-40 blend with LC and VSOT.
850 has wholly heck brew of 5W-30, 5W-40, 10W-40, LC and VSOT.

Both will get changed at 10K or 6 months/1 year depending on time/budget.

Pablo, 15W40 AND VSOT? My gosh man thats like tar

. Side note to Pablo, you dont have your Amsoil Distribator sign out yet anywhere near Big Rock Rd. DaveJ

 

[Pablo]

I guess I'll need to buy a sign!

I figure the LC added every 1K keeps it thin.

Hi

I thought that too about LC20 keeping the VSOT from going too far...but my drained M1 10w-30 looked like cold molasses sitting in the catch basin the next morning.

This trip, I used one oz of VSOT per qt of M7500 with LC20 standard dose added.

I use VSOT in 15w40 during the summer at .5 to 1 oz per quart in a 15 qt system and notice no appreciable thickenning of the resultant.
