I have a Mitsubishi lancer 1997 model with 1300cc engine which broke down at 250000 KM and started consuming oil so i rebuilt it and changed all the broken parts and started using 20w50 oil cause i live in Egypt which has temperatures that requires such viscosity as per the car manual, i have been using mineral oil rated API/SL and it says i should change it every 5000km but i change it at 3000km with filter on each change and i always flush the old oil but then i started searching for oils and differences between them and found out that 100% synthetic gives much better protection in high heats and crank start, now the question is can i change to Amsoil 20w50 premium protection as its the only synthetic with 20w50 in Egypt and change it every 10000km cause i dont want to keep any type of oil for long as the terrain here is rough and 80% is city driving with lots of speed pumps and traffic and of course the air conditioner is always on and 20% is traveling with full car and full luggage, i have uploaded the data sheet of the oil i am using now.
Sorry for the long post and thanks in advance for anyone who will help but i am very cautious after my engine has been rebuilt cause of my ignorance it was broken in the first place cause i used a monograde oil which caused the damage cause i didn't knew about the difference.
