MPG Issues

I got a new Tacoma, 2020 off road trd ... had the 2019 sr5 and it gave me good MPG around 18-22MPG when I would use cruise control so I’m accustom to using my cruise control so I’ve been using it for about a week now (the 2020 Tacoma) and I’m getting HORRIBLE MPG I’m getting 12-14MPG... even when I cruise at 65-75MPH has anyone had this issue?

 

First off....... You shouldn’t be using cruise control with a brand new motor. Have you not ever bought a new vehicle before ?

 

Yeah.. like I said my friend I had a 2019 SR5 right out the box.. What’s the issue with using cruise control? Never thought it would be bad?

 

Is it brand new?

 

Yeah brand new out the dealer both the 2019 and the 2020

 

Give it 1,000 miles then report back. And don't use cruise control - You should be varying speeds and rpm's for the first 500 (more towards 1000) miles.

 

The issue is that it’s brand new..

 

Can you elaborate on varying speeds? Please

 

You shouldn’t keep a constant speed for long periods during the motors break in period. Be fairly easy on it and try to vary your speeds when driving. You want everything to wear in evenly and for your rings to set in good etc etc. I used to put my brand new race bike on a dyno and set the rings / break it in with 30 minutes of my time and never have an issue......... But that’s a whole other level of gear head talk. Just read your owners manual man. Break in according to Toyota is the first 1k miles and it tells you in the owners manual what to do and what not to do.

 

I just re-geared my truck to 4.88 gears.

The break-in procedure for the gears is to drive 50 miles at a time for the first 500 and then change the diff fluid. Now, you don't have to do this part. However, the first 500-1,000 miles, you should drive on the freeway at various speeds. For instance, if you're doing 10 miles on the freeway, do 5 of those miles at 65mph, and 5 at 70mph.

It's not mandatory at all, but it just helps break in the engine, driveline, etc. Keep it slow off the line, don't rev it high, etc.

 

Aaaaaa thank you so much I didn’t know that to be honest I really appreciate the help guys!!! Learned a lot! Will follow instructions and I’ll keep you updated

 

It'll get better over time. Also, most (if not all) fuel stations right now are using winter blend gasoline. Every car I've ever owned gets worse gas mileage in the winter due to the blend vs. the summer. I notice at least 1mpg difference.

 

^^^^^^^^ Exactly that. I’ll also add that you won’t get a great break in by staying on the highway all the time. You need city driving miles mixed in there too. All of the stopping and going puts different forces on your engine that helps all your seals and parts become great friends with each other. Your brakes and everything find ZEN during your first 1k miles. Goofy way of explaining for a laugh , but that’s pretty much what happens when you buy a new vehicle

 

Hmmm very interesting good thing to know new knowledge

 

Unfortunately I gotta do highway right now driving to my trade school and back is the only option in the mornings but I will definitely keep that in mind and take different routes when I run my errands

 

Just another reason I’m glad I moved back to TN some years ago. Lol 0300 and I’m in shorts and a sweatshirt with a nice mild breeze.

 

^This^

 

Yup covered in the owners manual.

 

Try turning down the sensitivity of the adaptive cruise, at the default setting, it tends to over react. On the lowest setting, it works great.

 

Thank you!!! I’m gonna spend some more time reading over the owners manual
