Engine Sludge Build up / What causes SLUDGE? / Why you should CHANGE your OIL Regularly

Engine sludge build up; I cover what causes sludge and how it forms, and why you should change your oil regularly and how to prevent engine sludge build up. There are several other things that cause sludge, however, irregular oil changes is a leading cause. Some less obvious causes include: a clogged PCV valve, worn head gasket, consistent low oil level in an engine etc. It's always good to take steps to prevent engine sludge and remove the gunk from engine if it does occur. Hope you find this "what you should know about engine oil sludge" video, useful.

I must add that weather conditions contribute to the weight of oil we use..0w-20 in hotter climate like Nigeria will wear out the engine much faster even if the engine calls for it..a thicker weight is better..5w-30 at max..a bad PCV valve can also cause sludge build up..our brothers here don't check or change it at all..

Excellent tutorial. Straight to the point, no annoying music, logical layout of facts - subscribed.
What do you recommend for very low mileage use per year *around 1k miles a year) combined with short trips in severe conditions (dusty). I barely get up to temp and my oil filter is showing a grainy oily dirt. No buildup under oil cap, no coolant mixing froth, no vacuum leaks etc but checking with finger under oil fill top case there is oily grime I can remove. Besides driving more at higher speeds and regular oil changes am not sure what to do.

Oil and filter Perfect time every 3, 000 miles Synthetic or conventional, it doesn't matter. The best results forever and ever !!! Thanks!

As i see NG, i quickly subscribed asap. The video is very informative. my wrong use of oil has made me have bad piston rings. Now my car is burning oil seriously.

Ethanol in oil oxidises and polymerises to form sludge.
More frequent oil changes are one way to reduce this.
Or avoid the ethanol.

You can prevent and remove sludge formation by bonding a lubricant to your engine.

crappie oil don't get Pennzoil... from a new oil change about two weeks later it was all sludge. Good thing I checked my oil every couple days I flush that system .. and did a oil change with mobile oil.. yeah I've never had that problem with any other oil. Maybe it was a bad batch.. but I'll definitely not buy that brand again. It was full synthetic Pennzoil. Never had a sledging problem ever or since then. but yeah, I do all the service myself on my car. I've been changing it every 5000 since new. car at the time only had 50 K. Now I'm at 80 K.

How can I tell if I have sludged engine without opening the cam cover
