EliteEtc.com: Why does Exxon Elite turn dark very early in the drain interval? (This may be especially pronounced right after converting to Aviation Oil Elite 20W-50)

ExxonMobil: Because of the wide variety of additives used in a modern engine oil like Aviation Oil Elite 20W-50 and the manner in which these additives behave in your engine, oil color is not a very reliable way to determine oil quality.

As you may already know, impurities are created in your engine as a by-product of combustion. Aviation Oil Elite 20W-50 is formulated with a very robust dispersant to uniformly suspend these impurities throughout the oil so that they are removed from the engine when the old oil is drained.

Sometimes these suspended impurities cause the used oil to appear darker than other oils. This is a sign that Elite is doing its job to keep your engine clean.

EliteEtc.com: We've had a few reports that the wear metals in oil analysis increase immediately after converting to Elite. Is this due to the same phenomonon?

ExxonMobil: That's right, Lisa. This is usually a sign that Elite is suspending some sludge containing wear metals left by your previous oil. This usually returns to normal after the sludge has been solublized by Elite and removed from the engine.

The process takes only 2-3 drain intervals after which your wear metals will return to a more normal level, or even a bit lower due to Elite's superior anti-wear additive package.

However, please ask your customers to fax a copy of their oil analysis report so that ExxonMobil Technical Support can review each situation individually.

The second part could very well realte to RL or other oils with strong dispersant chemistry and or ester based oils.
