buell99 1 #1 Posted December 21, 2015 Hello, I just aquired my 1st horse, a D160. Does the transmission take 10W-30? Same fluid run the hydraulics also? Any help is appreciated. Thanks Share this post Link to post Share on other sites
tommyg 152 #2 Posted December 21, 2015 10W-30 is correct. And yes, the same fluid runs the hydraulics. Congrats on your first horse! The D's are beasts when they're running 100%! Make sure you post some pics. Share this post Link to post Share on other sites
buell99 1 #3 Posted December 21, 2015 Any preferences on what brand of oil? Wanna change the fluids a few times to clean it out. I will definitely get some pics up. Share this post Link to post Share on other sites
pfrederi 17,147 #4 Posted December 21, 2015 I would go with Walmart oil the first time and then replace it with better quality for the second fill. Unless the oil in there is nasty one flush should be sufficient. Share this post Link to post Share on other sites
buell99 1 #5 Posted December 21, 2015 Thanks for the suggestions. Im itching to get the fluids changed and some fresh gas in this beast. Share this post Link to post Share on other sites
tommyg 152 #6 Posted December 22, 2015 I ended up putting synthetic in mine in the end. Less of a tendency to thicken up in the cold. 1 Share this post Link to post Share on other sites

JackC 616 #8 Posted December 23, 2015 Straight from the horses arse. This is the maintenance sticker on the rear of my 1978 D-200. Many seem to prefer Mobil 1 Synthetic. Some believe the synthetics will leak through seals easier and believe it may be better to stay with dyno based oils for the older machines. Share this post Link to post Share on other sites

But only because Autozone had a great deal on it. I haven't experienced any issues with synthetic. I'm not sure if they were even available back in the 70's like they are today.
