Oil Charge at 7500 or 10k??

The engine generates ALL the power for the car, both the ice and the EV. Doesnt matter how many cycles that battery makes in 10k. All the energy comes from gas in the end.

 

well this is true enough if you live on the great plains ... otherwise you can harvest/reclaim and store kinetic energy what other cars can not do ... (climbing the hills goes the same for hybrid and nonhybrid)... there is still no other powersource though

 

True, you can reclaim it, but the engine made it in the first place. My point being: No matter what speed or what terrain you drive, I bet the engine runs about the pretty much the same amount of time for a given 1,000 miles. If you drive 100 mph it runs 10 hours, If you drive 50 mph it runs maybe 10 hours on electric and 10 hours on engine. Same 10 hours, but less wear driving slower? Anyone have a different viewpoint?

 

I get much better mpg if I drive slower like 45 mph. I could easily get 65 mpg. Just pretend that I could drive like this all the time, I can't image that I should follow the same oil change schedule as someone who drive 85 mph all the time. That's why I think oil change based on fuel consumption seems more logical.

Even though the electricity is generated from gas, the Prius still have two power sources and I could use just electricity at a given time. On a slight down slope, I could run on EV for a very long distance without using gas.

 

Mostly all true!

 

Outside of warranty I guess it's Thunderdome. My personal feeling is that 10K seems about right for the way I drive and the fact that it's a hybrid. Just sayin'.

 

It's hard to say what a good oil change interval is. I wonder about the environmental impact of manufacturing synthetic vs drilling for regular oil.
I heard 0-20 regular ( not synthetic ) oil is now available. I'm thinking of getting some if it is cheaper.

I remember telling my dad that the oil change interval does not matter just miles drive. He doesn't drive much per year. His car had a slow leak that went unnoticed. His car ran out if oil and the oil light came on. It only had 70k miles. The engine was not ruined but I learned that the interval could help people who have slow oil leaks and never check oil level.

There's no contest though about how much better synthetic is when it comes to cold starts. And if you want both oil & engine to last longer, it tends to make sense spending the extra for that.

Also, consider how long 4 quarts of oil will last you verses 4 quarts of gas. You'll consume the gas in about 50 miles. The oil will provide service for 10,000 miles... then it will be recycled.

 

Go with what Toyota states, they are the experts, and must have researched this and believe 10K miles is best for all types of normal driving, now if you want to do it sooner then do so, it will not harm anything.

Oil will always be drilled for, so don't lose any sleep over it.

 

Maybe. Or a good interval is greater than 10k miles but they wanted to help their dealers keep their service revenues.

I don't put more than 15K/year on my car, so I just change the oil myself twice a year, once in the Spring, once in the Fall.

 

It depends on where and how you drive, how short are the trips(does the engine and oil get enough running time to heat up ?), how humid ,warm, cold is your climate ?
I live in a cool dry northern climate. My shortest trip is 40 miles, so the oil gets warm. At 10,000 miles, the oil in my 10 Prius still looks almost new, just darkening enough to make it easier to see on the dipstick. The engine uses no oil between 10,000 mile changes.
!0,000 mile changes work fine for me.

 

And synthetic oil is either made from natural gas,(PAO base stock) or hydrocracked mineral oil, so all oil comes from drilling for oil / gas.

 

Sorry for replying to an old post but I put black tape over my 92 Honda Prelude's Check Engine light for the last couple of months. I'm not sure what's wrong with that? The orange light is very bright and distracting, and the tape is cheap, quick fix that anyone can do. It doesn't sound like you've had experience doing this fix so I don't think you're qualified to speak to it tbh.

Seriously though, my CEL lit up for a faulty knock sensor. do not know about Toyota but CEL's only come up in old Honda's for emissions-related things, not actual hardware faults in the engine. It took a few weeks for a replacement sensor to be delivered from eBay so I "solved" the CEL problem in the mean time
