Eastern VA. No such thing as too many Magnums. | Alan, this is a portion I pasted from that article you linked.
"they DO NOT recommend a detergent oil in the hydraulic system...What is supposed to be in the hydraulic system is either a 10W or a 30W non detergent oil... This tells me that there are a lot of people out there that are blissfully going by the book and slowly killing their machine's hydraulic system. Hopefully at least some of them have asked before they wasted a lot of money and filled their hydraulic system with the wrong oil."
This brings me back to what I said yesterday about CLEAR single weight oil with no detergents. I'm still leaning toward the ISO 100 oil which is a straight 30W oil specifically for hydraulic systems, very different from 30W engine oil. Have you got a specific opinion on this? I just put AW46 in my excavator too. Thats what the book said. Wonder if that was right? |
