Thread: 2 Stoke oil in a TD5

It is the old style mineral 2 stroke that does the trick.

I'll call foul on the syn two stroke Gary as Redlines excellent RL2 diesel additive uses an ashless POE lubricant in its formulation.

It's the best diesel additive I've tested in terms of used oil analysis.

I use Castrol 2T and I think from memory it says on the back of the TTS 2T (synthetic) "not recommended for air cooled engines"

I'm guessing that an air cooled motor could run pretty hot when not moving much and possibly burn the oil. I'm thinking the idea of 2 stroke oil is to not burn but lubricate.

Happy Days.

TTS is fine in an air cooled two stroke, it was the oil of choice back in the day in Yamaha KT100J Kart engines and is used often in chain saws.

I can't abide it in saw use as it stings and burns the eyes, it really is acrid, but engines like it.

I am only repeating the information contained in other forums (I have never tested the diesel to confirm) where it is claimed that synthetic does not mix well with diesel and is not recommended.

Most recommendations on the topic are for mineral oil - 2TT but I have never seem any real proof published as to its benefits - plenty of testimonials.

Many people claim quieter running, better fuel consumption, more power, less smoke - sounds a bit like a Hiclone . I have been using it for nearly two years and I have not found any of the above - I use it simply because it is cheap and may (not will) provide a little bit of extra lubrication to the injection pump and might help reduce damage if there is some fuel contamination - but then it might not.

Here is an actual laboratory test by people who know what they're doing comparing fuel additives, two stroke oil being one (rated 7th overall). Might be helpful reading if you can't get to sleep! Interesting that they state, in regard to 2 stroke oil, "may damage 2007 or newer systems".
