Oil/Fuel Dilution Concerns...

[MustardTiger]

Just reading over at the Land Cruiser forum...seems like some owners have noticed fuel dilution (~4.5%) issues and associated rising oil levels on the dipstick with the 2.4 Max. Anyone here having this issue? I know for me, since new, every time I pull the dipstick...there is a strong gas smell. And I have noticed variations in oil level...and never lower than it was before. Thinking maybe with the hybrid being on/off...fuel dilution is happening. I recently changed my oil, had the level right at the full mark...and in a short time, I've driven a 6 hour highway trip, and maybe 60-75 miles city. The oil level is now 1/4 inch above the full mark, and smells like fuel/gas.

Thoughts? Anyone else notice this on theirs?

I’ve owned several hybrids. Still own . If you make a lot of short trips it can be a problem. 20-30 minute trip at highway speeds once a week solves the issue. But the body on frame is an entirely different hybrid system, I thought I read some where tow/haul mode with the Tacoma Hybrid will keep the engine running at all times? Doing that a couple times a week would probably work to reduce the problem as well. I don’t own an iforce max but somebody will chime in?

@MT-Taco yea I've started using the tow/haul mode to keep the engine running. Because as soon as the coolant in to operating temp...that engine shuts off at every opportunity it can. I can't see the oil getting to temperature for most short trips

FYI Toyota dip sticks are not good, when I check my oil it’s always before the first drive of the day. I think it’s actually the tube that gets oil splashed into it?
