All about Two stroke (2T) oils

[babu.sundaram]

I usually use Castrol Power1 (earlier Jettx) for my RX135, for years now, buying it from Metro (no need to check authenticity & it is also cheaper!).

Just to try out (and avoiding Metro ..) I tried Shell. Surprise / shock, the bike seems to have some low rev preference, speeds above 55/60 make engine sound too stressed out. (Old commuter, unmod engine, used to have similar character above, 70..).

Anyone with similar experience? Would the engine get used to?

(BTW, both Castrol Power1 & Shell VSX claim API TC & JASO FC).

Filled more Motul 510 in my gun few days ago, further diluting the Jet X (or whatever it was called later) in the oil tank. Performance has improved even further! Not only has pick-up increased further, but even the vibes have reduced a lot! The ignition key that was making noise due to vibrations has stopped making noise. In fact I can now keep my finger on the speedo and feel almost no vibes!! Visible smoke levels are now next to zero.

No doubt this is one awesome oil and will blow away every other 2t oil in every paramenter... except maybe the fully synth Motuls. Anybody who tries this once will not even imagine using Castrol/Shell/BP/whatever else.

Shell Oils usually good. But I'm not sure what grade were you using. Try Motul 5100 SS oil for a change. You'll love it.

Ah! 510 is a good SS oil in that category. Run for atleast 50 kms since you have mixed. You'll love the revvs from then, Oops! I don't have to tell to a guy who has been in 2T section for a long long time.

They are bit expensive but worth it!

^^^I guess I must've done 50 km since the 2nd dilution. Wondering if things are going to improve further...

What I'm worried about is the future availability of Motul 510. Unless sufficient people ask for it, Motul will not import more crates. And if they don't then using Castrol and BP garbage again will be like going back in the dark ages...

Guys, I repeat - just try it out once and persevere in getting it. You'll never want to use anything else.

There was just one grade (The usual bottle green can) version. Would check and post it. I was a little reluctant to try Motul as for day to day use, but nothing wrong in trying nonetheless. Would try a mix at least and post back.

I couldn't help but notice that reference in this topic has been made to both Motul 510 and Motul 5100 oils.

Motul 510 is specially made for use in a 2 stroke engine.
It won't have the needed anti-foaming and detergents to make it suitable for use in a 4 cycle engine.

Motul 5100 on the other hand is made for use in the crankcase of a 4 cycle engine.
It will have ingredients designed for long term use in the crankcase of a regular 4 cycle engine but it will not have detergents a 2 cycle engine needs and it will not have the ingredients to make it burn cleanly leaving little or no ash behind.

I do wish companies would not make similar products like oil with only a slight difference in their product's name when there are important differences between them.

Oh well. We have to live with things like this all of the time so I guess making a mental note of the difference in names is our only option.

The 5100 could be used in the gearbox of a 2 stroke bike though. That's what I'll use at the next change.

Raking this old thread up, For my RD I currently use the Shell Advance NSX, Semi Synthetic. Would be keen to check on the performance of Petronas Sprinta if they are readily available in Bangalore (might be a dumb question to ask but Shell Oils have been good for me from a performance wise & cost wise 257/ltr).

Not a big fan of Castrol due to their high costs where the similar semi synthetic oil costs around 334 Rs to a liter.

Any pointers to where I can procure Petronas Sprinta and I generally stock up 10 liters as there is one more 2-stroker in my garage.
