T.W Auto Service is a car workshop at 3006 Ubi Rd 1, #01-390, in Geylang, Singapore, holding a 4.9 Google rating. A good mechanic is worth finding before you need one in earnest. When a warning light comes on or the brakes start to squeal, expect questions rather than guesswork — cold starts, wet roads, hard braking and other details point straight to the cause. Regulars tend to stay with one workshop for the life of the car, since a mechanic who knows its history can catch a slow oil leak or a weakening battery before either turns into a tow. It is fair enough to ask for a quote in writing before work starts, and to have the old parts handed back. For drivers around Ubi and Geylang, having a 4.9-rated workshop on Ubi Rd 1 makes routine servicing and sudden faults that bit easier to handle.
