Putz put in 10W40...Now what?

[Andor_imp]

I use what I find 10w30-10w40-10w50-15w40-10w60 ..... ..... I must say that I have never had any problems, very often trip to two with three suitcases, the important thing is that there is oil and replace at short intervals.
If I find the hair on the egg, I noticed that with the 10w30 after long trips, the gears change has become more tough, while the others are not oils.
