Engine oil recommendation. What about ARAL High

You should use the oil recommended by the manual.

Most ignition modules have a low speed and a high speed section. Perhaps the high speed section is bad.

make/model/year?
What do you mean by a long time?
What have you done to fix it?

yes 120 bucks

Well a lot of motor oil brands will have a high milage formula, I prefer synthetic oil for my engine but at 194k miles if you haven't used synthetic oil for the life of the engine it's kind of pointless to start using it now. On that model I believe the recommend change time for the oil is every 5k miles, I would start doing it at every 3k and not worry about synthetic.

personally i would advise staying with the manufacturers recomende oil, maybe go with a fully synthetic version

i would recommend something like mobile clean 5000 or Valvoline high mileage oi, im pretty sure that this car takes 10W-30 being the age.

since your car is older and mileage is high i recommend using 10w40 high mileage oil and and takes 5 quarts.hope this is what you wanted.

Most any 5w-40 fully synthetic oil with be fine in your car.

but here is a list of the recommended oils from Volkswagen.
