When Do You REALLY Need to Change The Oil!?
Hey, in this video I will tell you a few secrets about changing the oil. So if you want to learn how to maximise your engine's lifespan, then you should be watching this video.
Some manufacturers recommend changing it at 15,000km, some at 30,000km. These ones are the so-called longlife oils.
Honestly, don't change the oil at 30,000km, I will tell you why.
If you're currently changing the oil every 15,000km or 1 year, it's fine, buy you could do better than that. The best time to change the oil is between 5,000 and 10,000km. Well, maybe 5,000km is too early, but if you go on Nurburgring a few laps, you should change it in 1,000km.
Let me explain why this is so important, so critical.
When you start the engine for the first time after several hours... the engine doesn't have any oil at all, so no lubrication. It takes around 1s in average until the engine gets oil... but what actually happens in that 1 second is the most critical.
Tiny metal fragments will detach from the engine's components and they will circulate through the entire engine. That's the main reason why we have oil filters - they need to retain metal fragments from damaging the engine... but it can't filter everything, you know?
Constantly driving with those metal fragments in the oil will add extra wear to the engine, so the sooner you change the oil, the better.
As you may probably know, the oil has 3 main roles, but you may know only the first 2:
Cooling
Lubricating
And the 3rd one is to wash out fine particles within the engine and retain them in the oil filter.
Simple math - if you start the engine at least 3 times a day... this will result to approximately 1100 seconds in which the engine is running without any oil.
1100 seconds is equivalent to a little over 18 minutes.
AAAnd did you know that in about 20 minutes of running continuously without oil will result in Engine Failure?
The Guys from Carthrottle just did that, so feel free to watch their video.
Within 15,000km the oil accumulates from 100 to 300 mg of fine particles and guess what?
It makes the car even slower. Fifthgear has done a great experiment on this subject and after they did 3 runs before and after the oil change, they came up to the conclusion that the car was slower with around 1 second before the oil change.
A good friend of mine owns an Audi A4 B5 from 1998 which has 1.9 Turbodiesel Engine with 110hp.
He replaced the oil every 10,000km or even sooner and he drove the car continuously around 200km per day for the last 8 years.
The car now has almost 1.3M kilometers onboard and still works just fine. I will show you his car and even drive it in the upcoming weeks, so stay tuned for that.
So literally, the oil is the life of the engine. How could Dealers tell us to change the oil at 30,000km.
The last time I change the oil was at 9,000km, so knowing all this, when will you change your next oil?
