How to Reduce Oil Sludge

Oil Sludge is one of the most costly problems facing car owners today. More advanced engine designs often result in unexpected problems that cause sludge to build up in the engine’s oil system. The sludge is particularly dangerous on screens or in small passages, where it can cause a clog that prevents oil from reaching critical areas. This will ultimately result in catastrophic engine failure, which can only be repair by replacing the entire engine. Fortunately, you can dramatically reduce your chances of having an oil sludge problem. Simply follow these basic steps to help prevent your car from developing oil sludge.

Difficulty: Easy

Instructions

Things You'll Need:

• Basic tool set
• Synthetic motor oil
• Oil filter
• PCV valve
• Seafoam treatment

1. Recognize if your engine is prone to mechanical failure caused by oil sludge in the engine. While any engine can potentially develop oil sludge, some are more prone to the problem than others. If your car has an engine with a known history of sludge problems, extra care should be taken to protect your car from sludge damage.

2. Switch the products that you use for engine oil. Never use conventional motor oil if you are concerned about oil sludge. You should switch to a purely synthetic motor oil, such as Castrol GTX or Mobile 1. These oils may cost more, but they are much cleaner and will reduce the chances of sludge developing, as well as cleaning away any existing sludge. You should also use the largest oil filter that will fit on your car, to help remove as much debris as possible.

3. Change your oil frequently. Some manufacturers will recommend that you change your oil every 5,000 or 7,500 miles. Over time they have changed this to increase the frequency of oil changes. If you are fighting oil sludge, your motor oil and filter should be changed every 3,000 miles or 3 months, whichever comes first. Changing it more frequently will not hurt.

4. Perform a Seafoam treatment every 18,000 miles, or every 6th oil change. Seafoam is a brand of engine treatment that will push its way through the passages where oil flows. This cleans any sludge out and washes it into the oil pan, where it can be easily drained away. Not only will the Seafoam treatment help fight the battle against oil sludge, but you will probably notice improved gas mileage after using the product.

5. Take your car to the mechanic every 40,000 miles to have the engine flushed. Flushing the engine will completely clear any passages and make the inside of the engine like new. This treatment is done in place of the Seafoam treatment mentioned in Step 4.

6. Monitor your engine closely. If you start to see oil appear on the top of the engine, it could be an indication that your PCV valve has become clogged and is leaking oil. Replacing the valve is an inexpensive repair that can increase your car’s performance. Ignoring the problem could lead into serious problems. Keep a close watch for oil on the engine, and replace the PCV valve as soon as it is noticed.

Tips & Warnings

• Oil sludge can also be caused from engine coolant leaking into the oil system. If you notice problems with your water pump or other parts of the engine cooling system, get it repaired immediately. Putting off repairs could result in significant problems with oil sludge.
• The Seafoam treatment can be added to the oil, the gas, or to the vacuum lines. If the latter method is used, the car will produce vast amounts of smoke. This is normal and will stop after the cleaner is burned off. For fighting oil sludge, you will get best results by pouring the Seafoam directly into the oil crankcase.

on 9/30/2009 Something I just noticed, re-reading the article, on the seafoam comment, you mention to use Seafoam every 18,000 miles OR every 6th oil change. But, early in the article you mention/recommend synthetic oil. Are you saying to still perform 3000 mile oil change intervals, even with the expensive "synthetic" oil?

BTW, reading up on synthetic oils, I've read that some "synthetic" oils aren't really completely synthetic, even though their bottles claim they are.....I believe Castrol GTX was one brand under scrutiny....

on 9/30/2009 i support sea foam in the crankcase/oil. As noted on the can, you simply add 1.5 fl. oz. of seafoam per each quart of oil. Don't forget to factor in your OIL filter too. Most vehicles hold 4.5 quarts of oil, so 4.5 quarts * 1.5 oz. amounts to 6.75 fl. oz. of seafoam into your crankcase (the top of the engine where the oil fillter cap is).

Add it in, drive the car as normal for 100+ miles, DO NOT EXCEED 3000 miles with sea foam in your oil though....then go get your oil changed as normal.

This article talks of synthetic, I like synthetic, but I'd recommend doing a couple sea foam treatments in the oil before going back to the expensive synthetic oil.
