Gen 2 oil issue. it is known among most xB owners that the second generation 2.4 engine (in the 2008 to 2015 models) has a tendency to use oil once it gets above 50-60K miles on it. Something to do with defective original pistons.
I change my oil very frequently with both of my 2015 xB models (my wife and I own two), and I mean frequently, because for the last three or four years we average about 1500 miles a year with each and take them to the dealer for regular service at six-month intervals. Both cars now have a bit more than 20K miles on them.
Toyota will supposedly replace the problematic pistons under warranty if the problem gets serious, replacing the pistons with better ones. My question involves the date when Toyota realized they had a problem with the 2.4 engine, and whether, sometime between 2008 and 2015 they started using the better pistons at the factory. If so, our two 2015 models might not be having the problem up ahead.
If not, well, being retired, we do not drive all that much anyway, and my hope is that the oil being replaced every six months will not have enough road time between changes to be causing problems. We use dealer offeredToyota oil, which supposedly is synthetic from Mobile.
Anybody know whether the latest second-generation models (say, 2014 and 2015) came with the better pistons right from the factory?
