Hi Scotty, I’m going to be brave and change my own oil. The last time I had an oil change at the dealership they gave me a warning that I would need a flush next time as the engine was producing sludge! That shocked me as oil on the dip stick always looked clean as a whistle to me and the the oil has always been on the full mark. I only have have 80,000 kilometres however a lot of my driving is short distances and living on the West wet Coast of Canada doesn’t help.  I am disappointed that the dealer says it has sludge and needs a flush???  I did look down the oil fill cap and yes I see what I believe is sludge but it didn’t look horrible.
  Question Is Mobile the company that Toyota uses for their oil and filters? I see in  Canadian Tire Flyer that Mobile Synthetic Oil is on sale right now. Trying to save a buck, and should I raise the front of the car so I can get as much of this clumpy sludge out?

 Thanks.
