MOTUL ECO_NERGY SYN UPDATE

[TheSilkySmooth]

Our Family changed over to syn this winter on the yaris. Its a PAO oil( which I dont like IMO) these are some general qualitative experiences:
1) I'm not loving it too much in the cold - It cranks slow. how slow re: mobil 5000?Dunno. real s-l-o-w. Just expected better for a PAO designed for cold economy.
2) Power is down at high revs. runs good when warm from idle to (guessing) 4000rpm, but try to get on the big torque peak up high - it just falls flat. Some of this may be the WIX filter - the purolator we ran last OC had the best high rpm power of the 4 filters we've run: 1 oe denso, 2 siamese denso, 3 wix, 4 purolator.
3) Car runs consistent - no stuck rings no stuck valves. Same day-to- day, notice less susceptibilty to gasoline brand changes. Almost cant tell diff - where as with the Mobil 5000 and the Purolator it was sensitive. I'm not sure this is a good thing - engine may have DETUNED itself to deal with the PAO syn vis.

I'll let you know if it blows up - but I am pulling my recommendation for the cheaper MOTUL eco-nergy 5w-30 in this application pending more research on the effects of the filter. I may solvent wash the old purolator and try it for the last 500 miles of the Motul OCI and see how different the engine feels. MAybe just the filter (though that wouldnt affect cold start cranking)
