LPG Conversion..... Possible Issues by oNj(m): 6:04pm On Sep 28, 2020
I've been excited about converting my Camry to LPG.

My excitement soon waned when I went researching possible problems with LPG conversion.

Not to sound like an alarmist, but here are my findings:

1. You lose about 20 - 25 percent of engine performance. Ok fine, I can deal.

2. Valve Seat Recession: this refers to excessive/accelerated wear of the valve seats that comes from running on LPG. Though all valve seats wear with usage, no matter your fuel type, LPG accelerates the process since "vapourised gas has no lubricating and cooling effects". (www.amrautos.co.uk/index.php/lpg-systems for full article on this).

A way around this is to install "flashlube" on the engine to provide lubrication.
Well, this not only raises the running costs of LPG conversion as against it's main attraction -- economy, it's use in cars that are prone to valve wear often do not prevent this excess wear valve seat wears.

While not all cars suffer this LPG-induced excessive valve seats wear, the list is quite long. (Ref: www.amrautos.co.uk/database_problem_cars.pdf).

My car falls in the list above (Toyota, all models from 1998 is in the list) embarassed

I can't deal. cry


Divergent opinions are welcome on the viability of LPG conversion

Point is not whether any (petrol) car can be converted to LPG or not; the effect on the engine is the issue.
