PLS PLS PLS FOR THE LOVE OF EVERYTHING CHECK YOUR OIL IN YOUR CARE EVERY ONCE IN A WHILE
(Unusual ramblings from me so ignore if you want. Not Janaya or TDP related at all)
It happend again today that a customer brought in their car today because the turbo made some weird noises. Turn out it is broken be the costumer "forgot" to do their oil change at the requiered interval. They missed it by about 12000km (about 7500 miles for you freedom cheese eaters). WHICH YOU SHOULD NEVER EVER DO. Not with Gasoline and especially with Diesel powered cars.
Why does that damage the turbo you might ask? Well the turbo also needs lubrication just like the rest of the engine does so when the lubrication gets worse theres bound to be metal grinding with each other. Causing play in bearing which shouldn`t have any or very little. These small metal fragments will travel through the ENTIRE lubrication system and they will cause damage. There is only so much the oil filter can, well filter before its full.
It`s usually either by milage or by time but they drive ALOT so it was because of the milage in this case and they reset their oil change in the cars infotainment system themselves because I guess they found it annoying that it was blinking. They did however have an service note in their engine bay from their last oil change so. And I was able to check it in the Engine Control Module.
They werent mad or anything about it as far as I can tell but they just got themselves a rather big, unnecessary repair bill that was easily avoidable. So pls pls pls check your oil (and all other fluids for that matter) every once in a while and fill it up with the correct oil if its low and dont forget regular oil changes every year or every 20 000km/12 000miles as a general rule of thumb.
You can find all if that explained in the service manual as well!
