Been there. My real sympathy with all those packing up. -
It's completely true. Working for the bank and nothing else. Misery. Plenty with a million quids worth on the never never; how they sleep at night?!
-
Sorry thread title should be "in" not "is". Mods please correct my dumbass typo, I'd be ever so grateful.
-
Agreed

A few markers; cut and extract rates squeezed to the limit; cutter taking the hit as usual. Lorry drivers actually admitting they're quiet... 2015/16 particularly poor for firewood for obvious reasons. The phenomenal volume of used machines coming onto the market every day; mascus et al; even ebay has circa 10 harvesters on it at the moment. Tractors; just not selling (so say the dealers). Definately not favouring the big re-gen harvesting contractors. Crike.

:drool:

Quite. Blame the fuel! Why I now do a Stubby and put RL2 in Aspen 4... Use Ethanol Shield where I have to tho...
-
To clarify RL basestock is 100% POE, not a blend including some POE. Another thing; it's a race oil; designed to be used up fast! Doesn't like being stored for too long and has been reported to attract water. So dont make up 20 litres of 2 stroke mix with it nd leave it for 6 months! This might be one area where RL does not 'perform'. I am always seeing it from an extreme wear protection, heat and shear stability perspective.
-
For the second time; it's not just a "quality" basestock. Motul use ester basestocks. Only RL using Poly-ol ester. There is nothing better. I reckon Stihl ultra is fine for this industry too; but I'm not a lowest possible denominator kinda person. I do not accept that I was rubbishing other oils; merely pointing out some facts, not fiction. You need to do a Tribology degreee. I will see if I can dig out specs. Oh I almost forgot; in 1999 (PgDip) we did lean-off destructive testing of two-strokes as one part of oil testing; nothing much spectacular occurs but the 2-cycle oil contributes considerably to the longevity under such conditions.
-
Basestock! Stihl Ultra is probably very average. There are a LOT of oils between that and RL. AMS, Motul, Putoline, Castrol,... Watch the video link at the bottom of my posts.

More for RL junkies! [ame] [/ame]

This always makes me smile. Bit cheesy but the bloke is genuine. https://www.desertaircraft.com/collections/oil-recommended-by-da [ame] [/ame]

Nope: HP Super two-stroke engine oil - Top performance engine oil for two-stroke or 4-Mix engines Bizarrely HP Ultra is shown as FB; can't be right. There will be FC rated oils better than FD; or rather the maker hasn't been bothered to go for FD certification although the product would more than satisfy it. Echo exceeds FD; so does RL but is FC rated; probably lacking FD additives as it does better with the ultimate basestock.
-
HP Super (semi) and HP Ultra (fully syn) are both green so perhaps the latter you see? Both are FD. I don't endorse semi-synthetic in 4-stroke applications but for a 2-stroke is quite acceptable given the charge exchange rate. I'd like to know what group basestock the HP Ultra has; won't be group 5 that's for sure. PAO at best I'd imagine.
-
Only that silly size I'm afraid; larger canister only available in the US. I've petitioned them to no avail.
-
Yers; I am an authrorised Redline stockist. Poly-ol-ester basestock; there is nothing better. If only it was as cheap!
-
My arse is full of Redline oil.
-
£10.80 vs £9.74 (1L measuring bottle); why would you bother with Red?!
-
Ah, now interestingly, I think BP did indeed have lower ethanol content than 5%. I got a hunch that the combination of oil quality and ethanol burn are big factors in all the goings on...
-
You need those bars yesterday by the sounds of it.
-
Imo yes, especially as HP Super is only pennies more from the likes of Mole Valley Farmers. Red HP stinks like hell imo. Out of interest do you use Producer gasoline or Supermarket brand?
-
There you go; FB @ 3%. The better the basestock the lower the friction and therefore temperatures. Higher thermally stable basestock resists breakdown in the ring area and so provides improved compression and more scuff resistance. Add FC/FD detergents to further reduce residue build-up, altho cleanliness is a function of basestock quality as much as anything else. Basically, the better the basestock, the less additives / detergents etc required.
-
You were lucky. Latest gen autotune saws from S,H and D all state NOT to use mineral base 2 cycle oil in these engines. Seems reading the instruction / owners manual is a lost art.
-
Eh?! One minute you say "they're all the same thing anyway" and the next "we should be using premium". FTR, whilst a piston ring doesn't have a brain, it WILL 'know' the difference between oils - big time. Saying it doesn't is totally incorrect.
-
No; probably bust it yanking on the saw. MS460's were prone to doing this. Just put a new one on and check. Spud knows all about em.
