engine oil – Ramblings of a Singapore Biker Boy

Pulsar 200NS Engine Oil Anomaly

This is crazy… At the Sunday Morning Ride, I was just talking to a fellow biker about carrying an extra bottle of engine oil for a long trip. And when I returned home after the ride, washed and waxed by bike, I realized that my oil inspection window was… EMPTY!

I had initially thought it was still “warm” after the ride and allowed some time pass to allow the oil to flow back down. But checked the oil window the next morning, still empty – no matter how I tilted my bike. 🙁

So I thought the high RPM run on Sunday might have something to do with it. No external oil leak was observed. So my worst fear was an internal engine oil consumption – aka oil “burning” up. Was it an engine gasket issue? Perhaps a valve oil seal failure? But it was only 17,000km since my engine was rebuilt in Chiang Mai, and I’d be very disappointed if an oil leak or oil consumption occurred.

As a temporary measure, I added Continue reading “Pulsar 200NS Engine Oil Anomaly”

Why I use Motul 7100 instead of 300V

Time for an oil change. My previous Pulsar blood was a concoction of Respol fully synthetic 4T 20W50 (800ml) and Motul 300V 15W50 (400ml). The Repsol was what remained from the oil change when I was in Phnom Penh’s Bajaj dealership, and the 300V was what remained of the oil that I brought along for the long SE Asian tour.

To be honest, I did like the 300V. But my own research suggested that the 300V, while being an excellent oil, was really designed for “racing use” (only). At the recent Singapore Bike show, I had the opportunity to speak to the technical representative at the Motul booth. He confirmed my suspicion that the 300V was built for “racing use” and the 7100 4T was probably more suitable for my purpose – daily commute and touring.

Changed to Motul 300V oil

Decided to swap out the mineral oil in my engine previously used to flush the “teh-tarik treated” engine – coolant mixing with oil. Can’t wait to try this mix in my upcoming weekend trip…

Ironically, with the stock bike, the coolant appeared green and the engine oil looked red’ish. Now, my bike’s coolant is red’ish and the oil is green. Almost looks like I got the 2 liquids mixed up – putting them in the wrong refill orifice.
