Conquest00

Yeah the oil isn't sludgy or anything but I was going to flush the oil twice as you said in your second recommendation once I knew it wasn't a good idea to use any flush treatments. I tend to do stuff like this once I buy a second hand car :bash:

I think I'm gonna give the 15W-40 a try and if I see that the engine doesn't like it then I guess 20W-50 here we come! :S

I have a Corolla AE112R with 56,000k's and it's current oil doesn't look quite like golden brown, it's more a darker brown. Because I just bought the car I was thinking to run an engine flush treatment through before adding new oil. Toyota reckon that I shouldn't use their engine flush treatment because it could clean the engine too much causing more bad than good. Is there perhaps another engine flush treatment that I could use or should I just not worry about it and change the oil and leave it at that?

We've just bought a 2000 Corolla Conquest and I want to know which oil to use for it? Toyota told me that they used 20W-50 on them and they told me to keep using this grade oil. Should I buy the oil from Toyota? Which oil grade do I go for? Oh and shes done 55,000 on the odo :bash:
