Which oils?

Evening all.

I was just wondering if there are any particular types of 2 stroke oils that are recommended for running in, and subsequently normal operation of, a dle55 petrol engine? I need to buy some fairly soon you see.

Also, what sort of mix ratios are the best to go for?

Cheers
Andy

Andy I use Stihl 2 stroke oil as I use the same mix for my models as my strimmer and chain saws. My ZDZ's like 40:1 mix which gives a better seal on the rear disc valve which is peculiar to the ZDZ . Most guys running DA's and DL's ron 50:1 mix. I run my motors in on the same stuff I use normally but some run their engines in on a non-synthetic ashless oil for a couple of gallons saying that this speeds up the running in process ? You'll get as many opinions as people you ask, it's much like the Futaba or JR/Spektrum question it'll rumble on forever

I have no idea....

Roto recommended Motul 710 synthetic for my roto 25 in 2007

Motul changed that to 800 2T Factory Line Off Road
100% Synthetic

They say
"Maximum power and protection
800 2T Off Road was developed for the leading factory teams to ensure maximum engine performance. Formulated using anti-emulsification agents to prevent throttle valve jamming. Pre-mix lubrication only."
Stocked at Jonesies Motorcycles Kinmel bay just near the railway bridge opposite to road to Asda
50/1 mix grade 95 unleaded.

Just a comment here, PAW always recommend increasing oil to fuel ratio particularly with smaller engines. Simply because there is more sliding surfaces in contact per cc in a small engine (model) compared with full size (motorcycle)

Speaking from the motor bike side, IMHO, which ever type you start with you should stick with.
I wrecked a bike engine for the sake of a few quid when I put in some oil that was a different type (but had loads spare!).
BTW, I don't know the mechanics of the engine you're talking about but full synthetic can produce clutch slip in some brands of motor bike with wet clutches,

Love your honesty Sam, that's made me chuckle!

Cheers for the input too guys, much appreciated. I've been doing a bit of reading, including the DA50 manual (which is excellent!). Apparently it makes sense to run a semi-synthetic oil at 30:1 ish for the first couple of gallons, and a prop that allows the engine to rev freely (so slightly less diameter), so that the piston rings bed in nicely. After that, switch to a synthetic oil, at a mix ratio of about 50:1.

Watch out for the tree huggers!

I've tried a few different ones but these are for zenoah g260's and CY's but I've settled on using Rock oil semi synth from king cobra.
Valvolene is another good one but I preffer rock.
Mixture is normally 25:1 but I've always used 33:1 which translates to 150ml oil to 5 litres fuel.
I always use v power for 99 octane,well worth the extra few pennies.
