Just curious if anyone else has had this problem...I have a 2001 toyota Celica GT and when i first got it i drove it hard but after the last oil change i was taking it easy... than today after not even 2500km my engine oil was at nothing...and we checked the engine at the garage and there are no leaks...so I decided to throw synthetic in it now to see if that helps...man I am glad I put slick 50 in with the last oil change...I had 5w30 oil in it too and the engine only has 77000km on it...Any info would be a great help...
