Interesting, I've never used ultra myself, just because I've over half a bottle of super and a little more of xp left, but in intrigued why you don't like ultra. Stihl products normally work
Thanks for the post on Esso. I recently found a mention on Google saying that a certain Esso I can't remember and Shell 91 were E-free. I searched these further and came up with a blank. Maybe not available in the U.S.?Husqvarna xp, fully synthetic, or stihl super (green) semi synthetic at least, or stihl ultra (blue) fully synthetic. Run at 40:1 as a little extra oil seems a good thing to me.
I'm intrigued by the detergent additives mentioned above. Decent pump fuel should have those and I run our premium (super) as it's lower ethanol, in fact I run Esso as they guarantee e free super.
I saw Neil mentioned Esso. I remember it here back in the 60's. The name was changed to Exxon in 1973.Thanks for the post on Esso.

Good morning one and all. I lean to the right, so sometimes i just need to walk part way around a tree to have it agree.When you can't quite figure out where the lean is on that tree your about to cut.

I personally don't like the smell of Ultra. I'm sure many pieces of equipment live long happy lives with it. There are guys on here who claim Ultra causes hard carbon buildup. My 026 had a plugged spark arrestor and the piston top and combustion chamber had a thick carbon buildup. Based on that I could agree. It was tuned way too rich so I'm more inclined to believe it was a tuning issue. The Motul is a bike oil so it has more detergents to keep exhaust valves free. Sorry for the long post.Interesting, I've never used ultra myself, just because I've over half a bottle of super and a little more of xp left, but in intrigued why you don't like ultra.

Remember the Esso watchdog service vans with the German Shepherd on top? When I was a little tot I would sit at the window waiting for his arrival to fix or clean our oil burner. My vocabulary was like a broken record. What's that for? What does this do? Why are you doing that? I'm surprised he didn't stick a oily rag in my mouth but the regular guy was cool and taught me a lot. One time a different guy came and he was a grumpy ahole who kept yelling and pushing me away. It was a cleaning and he was doing shoddy work missing a bunch of stuff that the regular guy always cleaned. Wasn't happy at all when I pointing out all of the things he was missing. Never saw him again.I saw Neil mentioned Esso. I remember it here back in the 60's. The name was changed to Exxon in 1973.

I can confirm carbon build up on bone stock equipment that the dealer worked on exclusively. This includes saws, blowers, trimmers and a hedger. More clogging of the screens then anything. I never did understand why that was and the township kept buying the ultra. I know they say to run it in everything, but truth be told it was designed specifically for the 4-mix engines. Personally it gives me a headache. But that doesn't mean much.I personally don't like the smell of Ultra. I'm sure many pieces of equipment live long happy lives with it.

Neil, as you know I'm a Stihl guy, but that said I'm no fan of Ultra.Interesting, I've never used ultra myself, just because I've over half a bottle of super and a little more of xp left, but in intrigued why you don't like ultra. Stihl products normally work
I always thought Ultra was the stuff developed to run in 4-mix products to combat carbon buildup on the valves? Either way, I quit using it in my Kombi and it seems to be just fine with whatever I dump in it mixed at 50-1.I personally don't like the smell of Ultra.

I was at an auction a few years ago, and they had a full, 50 count, box of Esso pencils. I think they had the old, "Put a Tiger in Your Tank" logo. I'll have to go check. if they were Exxon I wouldn't have bought them.Remember the Esso watchdog service vans with the German Shepherd on top?

I think I started running Stihl Ultra in all of my saws when I bought my new 660 for milling. As we were getting the new saw put together I said I need some mix. He said grab some. So I picked up a 6 pack of 5 gallon bottles. He said do you use that much fuel? I said at least 5 gallons a month, sometimes 5 gallons a week. He said OK and threw it in the deal. I like that dealership. They won't let you take a saw out the door till it's set up and they start and run it. After about ten years my little MS 170 started losing power. I was at another Stihl dealer, where I bought a bunch of old saws, and told him I had never put a plug in it. So, he handed me a plug and asked if I had checked the screen for being carboned up. Duh, no I hadn't. Got home and pulled the screen out and it looked new. Then I looked at the ports in the muffler cover and they were about 99% blocked. Cleaned them out and it ran like new. But, that problem is with all oils. When Covid hit, I had a job scheduled and filled the tank on the 660. Got on the job and the people cancelled. I didn't need the 660 till Thanksgiving. Picked it up and remembered I had filled it 6 months before. 4-5 pulls and it fired right up. I let my old Homelite Super 1050 sit on the shelf for a year with a full tank. Same thing, 4-5 pulls and no problem. I don't mind the smell, performance seems fine, so I keep using it.Interesting, I've never used ultra myself, just because I've over half a bottle of super and a little more of xp left, but in intrigued why you don't like ultra.
