FWIW - The toyota is also a direct injection engine, which is not a signal for future problems. I have had a bunch of cars/trucks with direct injection and they have had no symtoms of fuel dilution.CULater wrote: ↑Wed Sep 12, 2018 8:31 pmIt has been reported for the 2.4 engine as well, as here (scroll down to #13):

I have no experience or first-hand knowledge of oil dilution problems with this engine. Far less has appeared than for the 1.5T engine. It does have direct fuel injection, which most other small 4-cyl engines also have these days, and my oil analysis report stated that "High fuel dilution can be common in direct injected engines." The extent of this problem varies across models and manufacturers. If I had to guess, based on the sketchy information I've seen, I'd say the 2.4 might well have the problem but it is likely to be less severe than in the 1.5T engine which uses turbocharging. My understanding is that the engine in the RAV4 uses both port and direct injection, relying on port injection for normal driving. Port injection is not known to have a serious fuel dilution problem and it also keeps the valves from carboning up, which can be another problem with direct injection. Me -- I'd buy the Toyota and avoid both direct injection and turbo. The 2019 is due out in November - December and it looks every bit as good as the CRV on paper.
These problems follow specific engine builds and not general engine designs.
