Block heat or not, synthetic oil or not

I can't comment on the oil type, but I would say using an EBH would definitely be advised. During the time of your commute your engine won't have time to heat up, so using the EBH will afford your better gas mileage during the short commute.

 

I agree with Tek about the EBH, especially given your short trips and climate. Many of us have bought ours from www.metrotpn.com. It is an OEM heater sold by Toyota Canada.

As far as the oil goes, I don't have firm scientific data, but there are anecdotal reports of a slight improvement in fuel mileage with synthetic. I switched at 5K miles.

 

I think the EBH is a no-brainer given your geographic location.

In terms of oil, synthetic is superior. However, it is also more expensive and may have marginal benefits when changed at the 5K intervals specified by Toyota. I recommend synthetic and use Mobil 1 5W30 along with a Mobil 1 filter and change my oil every 5K.

Welcome to the site. You definitely will benefit from the EBH. Blocking the grill and increasing the tp to at least 42/40 may help a bit. If this is all you drive you may not notice, but one is cheap and the other is free.

 

If I drove such a short distance I wouldn't have even considered a Prius.
You will be lucky to reduce your fuel bill by $300 per year over that of a camry or similar. Maybe an electric assist bicycle would have been a wise investment.

Good luck with it though, I'm happy with mine, hope you are with yours.
EBH is a must have or the engine will never get warm.

On the topic of synthetic oil, run the car for at least 5000 miles to run it in before switching to synthetic to allow proper running in.

This is not needed. Many new vehicles come with synthetic from the factory.

 

I try to be modern but am a little old school on this one. I'm a mechanic and understand all the stuff about finer tolerances etc but still believe that synth oil is best left till after running in. Just my opinion.
Of course that 5000 miles will take 2.25+ years to cover.
I'd also take the car for a few long drives in the hills to warm it up at least once in it's life.

You make the mistake of assuming that saving money on fuel is the only reason anyone has for purchasing a Prius.

On the other hand, if the original poster decided to purchase the Prius exclusively for the fuel savings they will likely be disappointed under the listed driving conditions.

 

You're right I made that assumption. You made the mistake of assuming it was a mistake. I also said I wouldn't have, didn't say the original poster shouldn't have, I made a suggestion that was my opinion and I hope no one thought I was putting anyone down for buying a great car. Perhaps you would like to calculate the green house gas reduction then how may trees could have been planted for the savings in buying a Camry? Both cars look great.

I really hope that wasn't the motivation, every time someone expresses disapointment in their fuel consumption the value of used Prius drop a little bit.

I wish Toyota would make a small, safe, comfortable plug in series hybrid for people doing short journeys. One with a plug in range of several miles and a constant speed petrol or low emission diesel generator to maintain the charge for the occasional longer trip. If fuel cells ever work out a simple conversion to fuel cell series hybrid.
