2004 nissan murano low 3 quarts oil. no sign of a leak and no smoke.

Always low? even if you have an oil change? If it's low at oil change, the mechanics don't say anything? Do you do it yourself? Do you change the filter yourself? The filter "absorbs" a half quart or so, if that is your perceived always low. Perhaps you have the wrong dipstick for measuring oil level? Otherwise, if you have oil in your Cooling fluid you have a head gasket problem between oil channels and cooling fluid. Greater failure may be eminent.

In the United States we don't use Kilograms as a measure of oil we use Quarts. Your country uses Litres wherever you are! THe MUrano uses 5 quarts of oil...you convert it to litres and you get .95 litres = one quart. Just use 5 quarts and all will be OK.

replace the valve stem seals

put three in then check dip stick..let oil settle before checking.if low add another.

excess use of oil is caused by only one thing a badly worn engine or one thats been hammered by a previous owner like a rental car or sales rep ,worn rings and valve guides are the main reasons for oil use ,ps whats a quart ?? whats that in proper measurements like how many litres and do not forget the trunk is called a boot .

hello. with a new filter, add 4 1/4 quarts of oil, US measure. The type is any good quality oil, API grade SG/SH. Go to page 249 in your owner manual for more details, here is the manual in case you do not have one http://www.courtesyparts.com/pdf/2004-Nissan-Murano.pdf

please mark my answer as very helpful. thanks. Joe

4.25 quarts

There will be a small (1/2 or 3/4") plug usually with a resessed 1/2" square drive about but just shy of half way up the rear pumpkin cover. Remove this plug and put your small finger in if you can't touch the fluid it is low. Usually a 90 weight gear oil but check your mnfg. specs. This will come in a gallon jug with a pump or a quart bottle with a pointed top. Fill pumpkin to hole.

10W30W, about 5 quarts with filter, add 4 and then top off after you run engine for a few minutes

Replace your valve covers do to clogged pcv piping
