Have you looked at your oil fill cap? It should tell you what type of oil to use. I have a 2002 Echo 1.5l and mine says 5w-30. I also have a 2005 Pontiac Vibe and it has a Toyota engine 1.8l that is slightly bigger than the 1.5lmotor in our Echo and it also takes 5w-30. I think you would be safe using 5w-30; however, I would look at your oil fill cap.

Hi,
Have you ever replaced the shocks / struts? Are you sure your tire does'nt have a bump spot or out of round? I usually will swap the tires front to back to see if the vibration or bumping moves, good way to tell if the tire is bad. I've gotten some pretty poor tires before, some do have factory flaws that will cause that. Shocks will cause that also. Sway bar pins / joints that are worn can cause that also.

Could be either the struts are getting weak or the swaybar links getting loose.

You will need the dealer that can't fix it,
to fix it.

Just love those dealers The dealer
maybe the only one that can get the code
using your VIN #

get it inspected, You may just have one sticking caliper that need replacement. the brake pads will be pretty worn on that wheel so you may needs pads also.

Yes because caster/camber and Toe can all be affected when you replace a steering or suspension part , also you have disturbed their location during the removal and replacement process, we are talking very small measurements but they are critical for good tire wear and vehicle handling .

Remove the engine & replace the seal.

first replace your fuse if the fuse burn again there is a short circuit cause of the hit search wire that is contct to the body of your car

bad gas
