I have 3/4 of a quart of LE607 and 3/4 of a quart of Bel Ray Gear Saver 90. Both are left overs from new bottles after diff fluid changes and are probably a few years old. Can I use them?

While I'm at it, I have 3/4 of a quart of Honda MTF. Same deal. Same question.

I have never been concerned about using them after they have been opened, and unused

I looked it up. Dont think it will be an issue if its only sat for a while.

I almost always end up with a half bottle of 10W-30. When I do the oil change, I drain the engine then use the half bottle to just pour some oil through there and if any is remaining, I add it to the new oil filter.

It seems a shame to recycle new oil. I think I'll shake 'em up good and use them.

Keep in mind that it sat in the ground for millions and millions of years. All they did in hte cracking process was to separate it from the impurities and the other brands.

There is a lot of hype on the internets about shelf life. Most of it from the oil companies.

Only thing that phases me on shelf life would be brake fluid.

Of course, they are trying to sell more product
