Btw your vacuum gauge posts got me interested in one. It's so fascinating how much info you can pull out from a single meter.
I shift up at 2,000 RPM in city traffic. That works very well for me. David I remember you said earlier that your mileage is only around 19,000 km, if I'm not mistaken. Mine is past 38k now, almost time for service. If you look at my Fuelly graph you'll see that my average consumption per month is dropping as time goes by. I remember about a year ago I was struggling to touch 400 km on one tank, and I was so happy when I finally did. Even then that was with super light foot driving, using very long detours to avoid jams, switching engine off at traffic lights, etc. Then I gradually kept hitting 400 km more and more often until nowadays it's virtually guaranteed. Now I can touch 500+ km if I drive carefully on the highway.
My theory is, your engine is still being run in, even well past 10,000 km. But then again that doesn't explain
how some people who got their car this year can start off so well
Also, I'm using relatively heavy oil, 15w50. Every time I ask for lighter oil the service advisor say takde

Cold tyre pressure, front 33 PSI, rear 31 PSI.
Hmmmmm yeah that was pushing it a bit too far. Though I remember reading somewhere that someone with a BLM ran out of petrol and when he tried to pump full tank it could only take 36 L. So maybe, 1.5 L from empty lah. I've never ran out of petrol before, and I don't think I wanna experience it

Absofreakinlutely no idea how those car behive that way. Driving style holds the 50% of the causes of fuel consumption behavior. Like my father style, he can do 20cent/km on a TOYOGA GRIUS. Funny thing is, regardless its a GRIUS from his friend, my BLM, my previous WIGA1.6, my ISWAGA 1.3, my brother's BiBA 850... he does exactly 20cent/km for all those cars. He's just so comfortable with his 3rd gear at 5krpm, even on high way. My mother once told me, how come your BLM sound geh? Your father's car sounds like a sports car you know "VROOM VROOM!"

Read my siggy, both car behave almost the same mileage. Before I had the vacuum stuck on my BLM, I can only do 250km/tank of RM60 fillup. After I put the gague, back to 300+. If translate it to cent/km or km/litre, it looks more or less the same with my ISWAGA

I developed to read vacuum since I owned a KE20

I'm talking about the car, and I'm not that DAVID. My previous magician taught me use that thing to troubleshoot my 30 years old engine.

David,
Sorry to hear about your problems with the Iswara this morning. Have you got any comments on what I said earlier?
No worries, am not going to overhaul the damn car anyway. Swap engine is definitely more worthy. Let's hope no debree left inside, so my engine can last for another decade

Taxi drivers run hundreds of km every day on NG, do you think they'll do that if it will damage the engine?
From my friend who installed the kit on his Iswara, you lose boot space, plus the car feels a bit more sluggish when running on NG.
Technically, natural gas will NOT hurt... UNLESS
1) Not enough gas feed in (result in burning lean and causes high heat)
2) Natural gas IS slaggy compare to petrol. The long haul of RPM rewing before the car start moving, that actually contribute to quicker clutch wear off.
3) If you run out of gas, you may switch back to petrol, but your A/F mixture will become TOO RICH, lots of black smoke and car wouldn't move, petrol consumption is 4x prior NGV conversion
My cousin is using the 1st batch BLM + NGV(if you remember the NGV package). His monthly gas expanses is around 100 bucks, with regular outstation travelling, another 100 bucks on petrol. He change engine oil once a month...some weird brand name with the rating of 20w50. And he's kinda enjoy playing with the switch, flicker back and forth. When pickup, switch to petrol, rev the damn thing up to 100kmh then cruise with NGV
