Did the first at home oil chage.
Oil changes are so dirty. I don't mind living with out them.
I got the Blackstone oil test sample kit to send off a sample.
Changed the oil at about 3,770 miles. The oil stunk of fuel, probably due to hybrid being too efficient for its own good.
Always turning off and often not getting up to full temperature on kind of short trips that a straight gas burner would have no problem warming up on.
I'm going to use the oil tests to figure out when I should change the oil. Might be 3,000 miles in the winter and maybe 5,000 to 7,000 in the summer.
This hybrid also has an oil to coolant heat exchanger, doesn't seem like enough.
I also installed a magnetic drain plug. Will see what it catches next change. It's barely got 11,000 miles on there so far.
Put in on a wix filter and regular flavored mobil1 5w-20 oil.
I'm going to try and find a larger filter, there is plenty of room for a bigger oil filter.

Why would you replace oil at 3770? Hyundai recommends 7500 miles.

The oil stinks of fuel. Probably from all the short trips my wife makes to work and back.
The oil appears that it may need to be changed more often in winter when cold weather and short trips are in play.
It should be able to go all summer on this oil change.

Looks like changing the oil was probably a good idea.



I left some wiggle room in this oil change. I filled the oil to about 3/4 the way up the full mark, in a few thousand miles I will add the last half quart or less in as 10w-30.

Blackstone Labs

That's very cool! In the Air Force,crew chiefs pulled oils samples every time a plane landed,for shipment to Wright Patterson AFB,where the lab would do what Blackstone is doing.With the data,they could more accurately predict when major engine service would actually be necessary.Glad you dodged a bullet on oil thinning.

Yeah my job pulled oil from the oil servicing carts to make sure the oil was nice and clean before it went back out and to make sure some dummy didn't fill the fresh oil up with used oil, which I saw happen at least a dozen times in 11 years.

.

I wonder if excessive fuel dilution is due to enriched fueling during warmup since it doesn’t run all the time and may cool in between being called upon to run.

You may want to buy a air fuel ratio gauge to see what’s going on. It may have a bad injector or not coming out of enrichment. Cheaper than a new motor.

Enriched fuel for warm up to get the catalyst going is very likey too. During the winter this car will drive around town with barely 3 temperature bars, which is no where near full operating temperature.

So for next winter I'm thinking grille block at the very least.
But I have to keep the high voltage electronics and motor coolant at winter temperatures if possible.

Maybe some sort of thermal layer or blanket for the block; retaining that heat in the engine could help keep the inverter cooler too. I've been tossing the idea around for my car, and found this person who did it on an Insight. BMW also experimented with an engine jacket a few years ago that they claimed kept the block above ambient for up to 12 hours after shutdown.

Its been 1,000 miles since the last oil change, about 7 weeks ago and the car is doing 42mpg with out even trying. I have been trying to sabotage the fuel economy when I drive it. I will put it in sport mode to run the engine more and get it to warm up all the way.
