Several problems can cause engine oil to burn. First, you need to figure out if your engine oil is burning, leaking, or just being utilized at a higher rate than normal.
Signs of burnt oil are increased pressure in crankcase, exhaust smoke, increased oil usage, and reduced engine pressure (caused by worn out valve seals). Despite the number of problems that may lead to burnt engine oil, you can check for some issues prior to calling a mechanic.
1. Check the covers of your valve. If your valve covers are not properly tightened, slow and non pressurized leakage can occur. See to it that the bolts are not loose but remember not to over tighten, bend, or crack the covers. To help avoid over tightening, use a torque.
2. If loose valve cover is not what causes the problem, remove it. Check your O-rings and gasket. If they have cracks, you should replace them immediately. Pop the O-ring or gasket gently using a screwdriver then clean any debris and place new gaskets.
3. Use an additive that helps reduce oil burning or increase the oil grade for your engine. If you are making use of 10W-30 oil, change it to 10W-40 oil. You might want to consider using a single graded oil. During summer, a 40-weight oil is ideal, and a 20-weight oil is great during the winter season. Regarding the use of additives, some experts have varying ideas and recommendations. Car builders neither discourage nor encourage the use of additives. These steps may improve the thickness of the oil making it more efficient in protecting engines.
4. Check the oil filter. Check if there is oil clogging in the filter or if the oil bypasses the filter. Remember, unfiltered oil, therefore dirty oil, burns more quickly than clean diesel engine oil. Make sure you only have one oil filter gasket. If you have an old one, see to it that it has been removed. Otherwise, you will have a leak, bad seal, or poor pressure. Replace your filter if it is old and functions poorly. Be sure to change it every time you change oil.
5. Change oil. This basic method alone can greatly lessen burnt oil problems. If engine oils are used for a very long time, they can become pretty dirty which makes it easier and faster to burn. Also, your choice of engine lubricant can have a huge impact. Some oils can remarkably reduce the operating temperature of your engine by up to 5 per cent (or up to 6-8 degree Celsius).
