Title: Re: engine oil light Post by jonnycab on Feb 13th, 2008, 1:18am Could be sludge/deposits in the engine or oil pump..... As scorpio_man says, it should be 5W-30 oil ;) Personally, I would start by flushing the oil out using a good engine flush (Wynns is pretty good) to get any sludge & deposits out of the engine oil ways & oil pump, & then refill with 5W-30 oil (semi-synthetic or fully synthetic).....& go from there :) |
