i have a 6KVA Chinese generator , and it runt for almost 10-11 hours continuously without any break, the company preferred in its manual to use 10W-30... i was using it for around 1 month without any problem, but as i live in warm city, someone advises me to use 20W-40, bcoz they say that as the generator run continuously 11 hours, so 10W30 will be very thinner after 3-4 hours, so i should use 20W-40 ... im very confused, plz plz plz help with it... wat should i use, 10W-30 ( according to manual) or 20W-40 ( as my 12 hrs running of generator and living in warm place)
please reply me.
