ano ang viscosity ng mineral oil? I need a change oil for my innova-gas and out of warranty na sya so i want to do the maintenance outside sa casa para maka tipid...since I have been doing maintenance in casa with mineral oil lang, what is its equivalent oil sa labas? need ko rin bang mag change ng filter almost 40,000km na ang na regsiter nya, what about oil flashing need ko rin ba to?

Since 5.5 liters ang need ng oil ko. what I intend to do is buy 5 liters of mineral oil and 500ml oil additive- ok ba to? just read STP oil additive, pwede ba 500ml nito will be added sa 5 liters or mineral oil? by the way gasoline yung innova ko...tia
