Well guys have a CNG cultus. The mileage is 20,000km. Ive driven it till 16,000km on petrol/hioctane and afterwards on CNG. Previously I used Shell Blue(semi synthetic) oil and replaced after every 3000/4000km.
Now that I am driving on CNG (and will be doing so for the future)
1. which engine oil should I go for? (Shell CNG yellow or Zic A/A plus)
2.WHich type of plugs are recommended?
Ive previously used Zic A in my baleno and it was vgood except that it was so thin that it used to leak out from the seal. I am afraid same may happen with my cultus.
Please guide me
