The oil service was done at Pete's @Kochi this time. The engine flushed and refilled with Liquimoly toptech. The oil filter, A/C filter, Fuel filter all replaced and the K&N air filter cleaned and put back. The OWS engine oil additive was added and also the diesel additive.
Did close to 900km since then - one Palakkad-Munnar (and back) and a few Palakkad-Kochi (and back). Yeti is super silent now and FE appears to have improved by some 2 to 3 km/L
I had a Tata Harrier accompanying me during a drive to Kochi airport last week. That guy was a spirited driver too and was struggling to catch up with my Yeti which was breezing at 140 kmph @2600 RPM. What a refinement post the oil service! One needs to do these speeds to enjoy the magic Bilsteins at work. The Harrier gave up after some 10 km or so. I was on my way to park the Yeti at CIAL before flying out to attend a 2-day conference near Hong Kong.
Will be getting the Timing kit replaced at Petes' too, mostly this Friday. Will update here then.
