the last saw i had 15 years ago was a husky, and nearly 35 years ago i had a large stihl. it wasn't the monster at the time but must have been 65cc/70cc. the big one was pretty rare and weighty. i remember the stihls having good power but drinking gas fast. now i will be getting a dolmar 510 or similar and wonder where gas consumption has gone in the last few decades. i have been out of the loop far too long. edit. seem to recall the 084 was the big one then. mine might have been an 072.
Probably was the 084 depends. Then went to 088 then to 880. Anyway I dont notice much difference than the husky or stihl. The big saws drink fuel compared to the smaller ones but they also do way more work in the same time.
It is reasonable to believe with EPA involvement and maturity of the industry that modern saws (Husky vs Stihl vs Dolmar pro saws of same size and power) have nearly equal fuel efficiency. Compared to older saws the efficiency is certainly better. As for big saws drinking more its obviously true. But I've concluded with lawnmowers (and probably saws too), you can get a smaller mower that burns gas slower and give it all up by taking longer to do the same job. The bigger faster machine gives you time that either generates more profit, more personal time for you, or just a wider grin while doing it.
Because they produce with the same standards, the same technologies, the same materials just diferend shapes and colours
Reminds me when my eighty year old dad was filling up his diesel pushing motor home. Young man filling up to him ask what his fuel mileage was. Dad said if I was worried about fuel mileage I wouldn't have bought it. Least of my worries. Having to much fun to care. Just my .02
Only thing I can say is the emissions have been reduced from years past if the saw is left in pure stock form...the marketing info from stihl and husky say better fuel economy...
I don't think the 510 is a strato design so fuel consumption will be a bit more than a saw with a more modern engine. Also I'd ask some of the Dolmar fans on here if the 510 comes with a catalytic muffler and if it's easily modified to remove the catalyst or replaced with a plain muffler. Cat mufflers make for a quiet and clean running saw but are bad news for power output. If fuel consumption is something you are concerned about, I'd look at something like the Husqvarna 545.
Ditto a Dolmar PS-6100, Dolmar's one strato-scavenged model. Of course a 30 oz tank helps- almost a quart.
The Dolmar 510 has a catalytic muffler going by this parts list, as it's the same muffler as my 5105 and it's definitely a catalytic. It weighs 7 ounces too. I have seen instructions for removing the cat and that a 5100 non-cat muffler fits. Mine is still on warranty so I'll live with the cat for now.
If it was mine I would pull the OE muffler and install the non cat muffler. Keeping the cat muffler for warranty returns. But honestly has anyone here ever had a saw with a warranty issue? If it were mine I would do what I said. If it were to break I would want them to fix it. Buy I also would not be too worried about it.
clemsonfor Yes someone has had a warranty issue. I had my 562 xp in the shop for longer than it was out (about 9 months in the shop) a few years back under warranty. They couldn't figure out the electronics and the dealer didn't have the computer program to work/ diagnose the issues. DexterDay took a few trips into the dealer for me since it was his local dealer and 2 hours from me. But now all is well (this week she started) and I love the saw but it was a love-hate relationship in the beginning but got me to buy a 372 in the down time of the 562 to keep cutting and now I have 2 nice saws.
This is the boat I am in. A couple oz saved at the end of the day? I'm not real worried about it. Because my saw may have drank more, but it was likely faster and got me home quicker. Clem, That 562 was a nightmare and out of warranty to boot, yet they (the dealer I bought it from) covered 100% of the time and materials because of the time that it took and the wrong diagnosis. The saw would start and idle for a minute or so. But as soon as the throttle was touched? It died. They treated the saw like an AT saw and just started throwing parts at it (new carb, coil, etc). That didn't work. So they finally broke down and bought the software (they never had a AT warranty saw until this one). Once they did that, they seen it was getting to much air. The dealer finally broke it down and found that the PTO side bearing had blown apart and tore the seal (one piece on that saw). That bearing destroyed the piston, cylinder, rings, etc. So in the end, it had new bearings, seals, piston, cylinder, rings, and every part to do with the AT system (carb, coil/ignition, etc). When they handed me that saw, I was expecting a bill. The owner told me that it was on them and that we both learned a lot. It's a great running saw. But at the time, chbryson and I both wanted them to buy the saw back. We were both worried it had undergone to much time, money, etc.
I've been thinking about a 5100 muffler. As I recall removing the cat from the 5105 muffler isn't easy with the tools I have. My MS170 croaked while it was on warranty. I'd bought it from the local John Deere branch store. They don't fix chainsaws there but they packed it up to the main store. It was back in a couple of days but with no explanation as to what the problem was. It's ran fine ever since.
Sounds like it came to the best possible resolution. Buying back an out-of-warranty saw is a pretty tall order. While the dealer should have invested in the software earlier, completely rebuilding the saw on his dime is as good of a solution as it gets. It probably would have been cheaper for him to just hand you a new saw in the very beginning but once you have a few parts invested, that option fades away.
