What has 750 miles of Mobil1 done to my BMW 128i? Field test Mobil 1.

[@gregnutter4658]

it's the cleaning agents in the oil. it means the oil is doing its job.

[@TenzaMotorsports]

Correct

[@andym1162]

that's right ,I agree with Greg, oil is doing its job.

[@markwarnberg9504]

The color change is to be expected when you switch brands as different brands can have different detergent additive packages. Switching brands once in a while is a good way to keep the engine clean.

[@TenzaMotorsports]

Right that’s why I pointed it out. I don’t think the Shell oil BMW uses has the same detergent levels

[@mohammadayub2760]

I bought a volvo high mileage went to my local garage I told him I need oil changed plus b4 oil changed I put 5 litres of flushing oil wow 7 litres came out I was surprised then he put in new oil my car ran so smooth the oil stayed so clean up to 1500 miles brilliant ❤️❤️❤️

[@karenchristiansen46]

Well you see I am an expert on oil and I am going to make a outrageous comment on how you're not doing things right and put some inflammatory words in my comment. But really I am just writing a comment that says nothing important. Keep up the good work testing the oils.

[@TenzaMotorsports]

Karen H thanks for the comment and support!

[@PilotCyrus]

I don't think that those oils that meet the BMW specifications are any different for the engine performance. My german BMW dealer uses a different brand almost every year. The car made over 150,000km so far. No repairs yet. Just oil changes.

[@TenzaMotorsports]

As long as it’s all the same weight and synthetic I’m not sure how much it matters

[@coynor1]

That’s because those oil filters are crap use OEM Mann oil filters only! That brown tint in your new oil is fine there will always be old oil no matter how long you let it drain, especially if you have a oil cooler. Plus that’s what additives are added into oil for “cleaning” if your that worried about it start using liqui moly 2 step oil additive process first step has a engine flush

[@pi1797]

Interesting video. I have always held the belief on oil changes. I like my old oil coming out very dark or black. Why? That tells me the oil is doing it job of cleaning the motor. I don’t drive new cars, most of my vehicles are older. So I expect the dark or black oil color at my oil changes. What is the brand of Shell that BMW requires? I have a friend that has a BMW X-5 and at his annual oil change the dealership was using 5W-30 Gold bottle Castrol.

[@TenzaMotorsports]

I’m not sure what tier of shell BMW uses. when I asked them, they kind of beat around the bush and then didn’t really answer the question.

[@damiansutube]

Castrol was the supplier and recommended brand for BMW for many years. It was the recommended brand in the owners manuals for BMW and Mini until the switch to Shell/Pennzoil some years back. Depending on the vehicle and engine the recommendation is typically 5w30 and more recently 5w40 BMW LL-01. As long as it meets those requirements the brand is splitting hairs. However in recently some oils that previously held the BMW LL-01 accreditation no longer do including Castro’s oils that once did for example. This makes finding those oil at your local auto parts shop much more difficult.

[@davidcampbell1899]

I was surprised to see the deformation of the filter after 750 miles. this tell me the filter construction is no good or there is some sort of a high pressure problem with the oil, like starting the car at -30F without a block heater, or something. I was also amazed how dirty the oil was, there is defiantly something going on inside that engage!

[@andym1162]

that's the mobil1 cleaning the inside of the engine, and the filter is now picking it all up.

[@kllimbrick]

Do the same test on a new car and it will look the same. If it does not, the oil is not doing its job. If anyone here has enough money to buy a new car, be sure to run this test and take pics of the color change,

[@unprofessionalmechanic8466]

I have similar issue with oil darkening on my Audi TT, but becsuse we bought it with 40k ml on it already, I do not know how maintenance was followed with previous owners. I am planning on using Lique Molly engine flush in old oil > change oil (something isnt expencive, like wallmart brand may be)+new filter with Engine flush again> and then put AMSOIL European formula 5w40 which I already ordered with their filter.

[@mohammadayub2760]

Hi when I get my oil change I make sure that wen I go to the garage my cars engine is hot I put it on the ramp my makanic who is my friend taks the old oil out then he put the sump plug back then he fill 5 litre of flushing oil in and at least 7 litres come out then he puts in mobile 1 and the new oil stays clean for at least 15000 miles plus my car runs like new OK it's a lot of messing around but believe me my car will have a lot mour po in beautiful

[@monroebass2]

I think if you first flush the engine as Amsoil recommends, you will find it has the best properties of any oil. Numerous tests have confirmed there is no comparison.

[@TenzaMotorsports]

I will look into that.

[@bhcrls1]

Surprised at the color change. Good information!

750 miles?… That’s pretty dark id say. You still have 9,250 miles to hit 10k and it’s already that dark. 🤔

[@TenzaMotorsports]

That’s what i thought too. I’m keeping an eye on it as I continue to drive

[@jesusthug]

Why not just use BMW motor oil? It has the perfect blend of additives for those car's.

[@nycalien]

@@TenzaMotorsports RP purple color always scares me to put in my engine. After a few minutes the purple turns to dark. Does that mean the filter cought the dye and got clogged.

[@in54ne82]

That oil filter is aftermarket garbage! How can anyone test the engine oil, which one is better or not. My Acura tsx has 220000 miles and I use whatever synthetic oil I have, 5w-30 or 0w-30. My bmw 135i has 140000 miles Ive used bmw engine oil, castrol, mobil1 so far. I track the bmw too. I change the oil every 5k miles on all of them. On my n55 335i I have 140k miles too with zero issues.

[@janekbrat]

Amsoil European formula is the best

[@SpankyCool-ib3pc]

DO NOT .. Change oil at 10000 miles. Mobil 1 10w30 is what you should be using. Change at 5000. Period. K&N Filter. Nitro Joe.

[@thomaslegay3108]

The best oil is amsoil my friend 😉

[@TenzaMotorsports]

I guess we will find out.

[@ricktaylor3748]

@@TenzaMotorsports You realize the crank and oil pump is full of dirty oil. You can't completely drain all the engine oil, when you change your oil. That's why that excellent Mobile 1 oil is somewhat lightly colored. Aside from going through 20 or 30 heat and cool down cycles.

[@TenzaMotorsports]

I’m aware. But it doesn’t have that much in there. Not enough to make 6.5 quarts turn dark like that.

[@ricktaylor3748]

@@TenzaMotorsports That oil really wasn't dark, it's normal for 750 miles. Any oil will have that brownish color, after cooling and heating up 20 0r 30 times.

Actually, Amsoil isn't the best. It's a very good oil but Mobil 1 is just as good as Amsoil if not better.
