I thought that all of them Sigma's regardless started to use oil more early then most 4cyl, i do not know why truly soft rings ? one dude claimed the ring tension was less ? but i thought molly rings ?
But i remember one dude that bought a new Sigma and it started to use oil and had just bought another new Sigma and they claimed the problem solved with his new 1984 one ! it was all BS thou.
I believe in getting up a new engine is a must do, run it in hard if you don't want it to use oil.
People who pussy foot a new engine is the worst thing you can do, as they can use oil.
But i think all Sigma engines used oil regardless from maybe 80,000 km or more say.
The size of the bore in 2,6L was the same as a 2.0L and even V8's with 4 in pistons plus do not use oil.
