I had very bad experiences with shell almanza in between good year and TS Cruz and not southmall. I had a radiator problem with my previous vehicle, instead of putting silicon lubricant, instead they put a stopper to the clutch fan w/c was a very big no no. It cost me an arm to repair it, 20k bnew. Bad Bad Bad!!
Another one, I had an engine wash with my other car, it stalled and it took half a day to fix the problem. sheeesh!
I strongly recommend the shop near the bf homes entrance beside Toyota alabang, they're good. I think the shop's called HONEST.
