Car Forum / Mercedes-Benz Cars / January 2007what type of oil should i use in a 1985 190E?
ive been doing oil changes on this car myself.. but recently got t thinkin what kind of oil am i suppose to be using? i have been usin 10w30 oil. the car has over 200k miles.. still running like a champ but anyone know what type of oil im suppose to be using -- MBENZ0 200K miles and runs well; why argue with success? Change the oil and filter every 7,500 miles; use 10 - 30 until the motor begins to consume oil, then move to higher viscosity oil i.e. 20 - 50 etc. ..... trick question? cheers, guenter >ive been doing oil changes on this car myself.. but recently got to >thinkin what kind of oil am i suppose to be using? i have been using >10w30 oil. the car has over 200k miles.. still running like a champ. >but anyone know what type of oil im suppose to be using? Keep using what you have been using. I would adopt 3000 to 5000 miles for regular oil. Tiger Wrote: > Keep using what you have been using.

Okay at this point I would do an experiment. I would change the oil to synthetic 5W40 and drive it around. First couple of hours would sounds like it is so much worse... but then afterward. it should quieten down... engine will run much smoother. If the tapping doesn't go away, then you got a different problem... which is wear and tear of the camshaft. This is easily checked by pulling the valve cover off. The reason for synthetic is that the oil channels to the hydraulic lifters may be clogged by regular oil coking and by running synthetic, you can clean it out somewhat but the oil flow to the lifter is much improved thereby closing up the gap that cause the tapping noise. |
