First oil change smells like gas

I never understand when people say their oil looks "fresh" when they do an oil change. I've never experienced this. In every vehicle I have ever owned the oil goes in golden and comes out dark after 5 to 6k. My Tacoma has 220k as of today and the oil will look just like yours when I change it this weekend. I'll try to remember to take pics.

 

Agreed. Same here. My point was that at 1000 miles on a brand new engine, my oil was pitch black and reeked of gas. That was the thing that wasn't normal to me so I wanted to document it and see if anyone else had the same experience.

 

Makes a ton of sense. Except Toyota is one of the worlds' leading engine builders and they fill their new Tacomas with synthetic oil off the assembly line. Toyota doesn't seem to care as much for performance as they do for dependability. That's clear by the booming aftermarket tuning options and throttle response products. They fill their new 2GR-FKS with the same oil for everyone. My question is/was, why did my result differ so much if all the variables were the same? We all got the same engine, same oil and it was "broken in" as instructed. I don't know... That's why I came to TacomaWorld.

I just wanted to document it in case anyone else had the same experience and for future reference if anyone has the same issue again. Probably not since this is the last year of the engine. I think it's going to be just fine and the truck is running great. Following your logic, it might have been better had I not changed the oil so soon and let the darn thing sort it out.

So the moral of the story is one of two things,

A) Change your break-in oil (in-spite of Toyota's assurances that you don't need to) and get rid of any contaminants that might be present from manufacturing or gas that has mixed in due to rings not sealing yet.

OR

B) Leave that shit in there and let it cook!! It will sort itself out soon enough.

I guess it comes down to your personality type. Do you fk with things or do you and leave it alone.

 

Why 5w-40 instead of 0w-20? I used to use mobil 1 for decades. Switched to Valvoline.

 

The problem is normal people think they know more than the smart people who designed the engine and the truck.
Follow the manual. Rest easy.
I trust those guys and I am an engineer.
I've been changing it every 10K just like they recommend. Zero issues.

 

I ain't buying this.
Most likely the engine was flooded at the factory or at the dealer. They finally started it, but were lazy to change the oil.

 

One of my favorite oils is mobile 1’s European formula. It’s also what Porsche uses, fantastic stuff with a lot of additives. Our engines are rated up to 15w40. I live in GA and the summer is hot. 0w20 is CAFE / MPG oil and does not protect as well against engine wear and fuel dilution.

Thicker oils are meant for colder climates. I use 0w-20 in AZ. It was 117 today; truck ran just fine in those temps.

 

You have that backwards. Look at the cart I posted. The first number in the oil rating is cold viscosity. The second is hot. But a 5w or 0w -40
Is ideal for any climate. 5w is rated to -30c

 

I understand the ratings. Seems like the truck would work much harder with 40 weight over 20 weight in the summer. (Like turning up the tension on an exercise bike.) 0w-20 works just fine for me.

 

Geez guys, just follow the fucking manual. You are not smarter than the Toyota engineers. You are not! Trust them or buy something else.
You guys think you you know better. You don't. Really, you don't know more than them. You actually know nothing compared to them. What you do know is you own it now. You trust yourself or do you trust the engineers. I personally trust the engineers.
But, if you think you know more than the engineers, then quit asking stupid questions and, because of your superior knowledge, do what you think is right. Change it every 100 miles. That is better right? Your logic sucks lol.

 

maybe after a sex cigarette they will have some enlightenment

 

I really trust the engineers that programmed the 6 speed auto …
and
I really Trust the engineers that did the 3rd brake light
And I really trust the engineers that designed a V6/ that gets V8 fuel economy
Aaaaand I really Trust the engineers that designed the front timing cover to be leak free
Engineers are flawless human beings sent by the gods to enlighten us with their endless knowledge and wisdom

 

You do realize that 0W-20 is CAFE / EPA based and not engineering based, right? Why does Toyota recommend this weight only in the US? I suggest you read the article I posted, if not already, and you will get some insight into why this is happening. And no, in hot climates and under load it is not a smart plan to use thin oil.

 

I’m not suggesting you change anything but I think it’s important to understand how viscosity works. As oil heats up, the hotter it gets the thinner it gets in essence. So, in a super hot climate when using thin oil it offers less protection to the motor because it becomes extremely thin and can fracture. This is why in hot climates it is normal to run a 30 or 40 weight oil. Also, thin oil has less anti wear additives. There is a huge push to meet MPG ratings by manufacturers and unfortunately, it’s at the sacrifice of engine wear and protection. 0w-20 is EPA / CAFE based and has nothing to do with motor engineering.

 

I agree it's way more golden, and clear when just poured from the jug. It's usually looks like a dark amber maple syrup when it's time to change it....not that it really looks bad dark as tar. That you'll always see in gm engines.

 

I think for one it's something to do with the cold winters we can have here in the northeast. What might be good for the southern u.s., isn't up here when I tried 5w30 in my tacoma last winter. The engine made a really weird sound upon start up one -15 morning. I won't be running that weight oil again when it comes time to changing it this fall. I don't care what the chart claims, it didn't happen the previous cold mornings with 0w20.

 

To you and the guy above that has trust issues... Fine, don't trust the Toyota engineers. I understand.
So, who you gonna trust? YouTube yahoos? Oh wait, your accountant dad?

That article you posted? Who wrote it and why did they write it?

I have and idea, why not trust facts and results? There are about a million Blackstone lab test results on here. Some were taken at 10K, some at 5K, some at 3K and some at 1K. Guess what the differences were...
Nothing.
So, go back to doing what some of you do best, like selling real estate and working in offices and plants.

 

Again, you are not addressing the obvious point I’m making. Buy the truck in San Diego and no oil chart, buy the truck in Mexico 15 min away, oil chart. Like beating a dead horse. Must be those Mexican engineers… lol

 

Of course my friend, 0w is meant for cold weather, 5w is meant for warmer weather. The fist number represents the viscosity at any give cold temp. If you live in a cold climate, you run thinner oil.
