Haha...I took AGIP Diesel Engine oil

as I could only get that. The guy also offered me 4T on Shell, but I did not consider that one. I choose AGIP Diesel because of my previous experience from Castrol CRB & Yercaud trip. I'll post the pic of Engine oil tomorrow.
Meanwhile, the update I posted in the morning are...
1. Airfilter cleaned up using Rin & Surf

& sprayed 2T oil. The result is amazing. I've the pic & will post tomorrow.
2. Washed (rather wiped) using Sonax car shampoo

& applied Waxpol on tank, swing arm & L brackets
The only pics I've to post are AGIP, air filter after cleaning with rin/surf & then applying 2T oil.
Trust me, the result is excellent to clean the air filter with rin/surf & soak in 2T rather than cleaning the airfilter using petrol. Amazing thing is that the wrinkles are gone now & looks like brand new. I'll post the pic tomorrow.
