10W/30 would be better as it is thinner than 20W/50. What we are trying to do is avoid thick oil during the winters that you can get over there. You may be fortunate enough to live in a more moderate climate and then it doesn't really matter as much, but that is why we tried to get away from the GL1 type oils that are very thick when cold and do cause unnecessary hydraulic problems. Using the 10W/30 could cause problems if the hydraulic system is badly worn as it would be thinner and it would leak more easily, if the system is in a normal condition then it wont present any problems for you,unless you get high weather temperatures it will be OK to use.I must say that I am surprised that you cant get 15W/30 low detergent oil in your area, we have had a lot change over to it, I must find out where they get it from and what brand it is...John
