Hello,
I had initially put in Shell Helix Ultra 5w30 in my Belta 2007 model when I purchased it in August, 2012, but today changed it after 8 months as it had done about 4,100 kms. The oil was not in that bad condition but still i replaced it due the the duration.
I replaced the oil with Shell Helix HX5 10w 40 due to the hot summers here in Pakistan as 5w30 is quite thin and unnecessary for this weather.
After how many kms or months should I replace it? I also used the local air filter and plan to replace it every month. Is that ok?
Would appreciate feedback please.
Thanks
