I have read your forum with interest. Can somebody amongst you oil experts tell me if the aluminum & silica levels are high for a vehicle in the country/rural area that spends 1/3 of it's time on dirt roads. The operating temp range has been between -10C~+52C during this last service period. The air filter is a double oil foam filter as the paper filters only last 10000km out here.
Does anybody have the anaylsis/composition of new De**ac 1?
Thanks,
Mike
