Should I change the oil althopugh it was done by the garage that changed my cam covers (they said 10/40 was used).I have just cleaned breathers but still get some condensation around the oil filler cap resulting in mayo. Must say car does not more than 3 miles on most days...dipstick (clean oil) and coolant are fine.(V6 2.5 cdx 98)
That is very low mileage for any car, let alone a 2.5 V6 Lou.

Your oil changes should be frequent as the engine is rarely reaching it's maximum temperature so contaminates are entering the sump. In addition your exhaust system is not adequately drying out as it does after a good journey (at
least 20 minutes), with your battery having more power drained from it in the start up process than being put back by unstopped running (again minimum 20 minutes without loud of lights, window heaters, etc.

My advice is that you should take the car for at least a good 60 minute run per week, especially in the winter months, and try and avoid unnecessary starting and stopping of the engine.
