Auto service in Banja Luka. Auto Gas Gaga, with over 30 years of active experience.
Auto Gas Gaga has been running in Banja Luka since 1996. Mechanics and diagnostics, LPG installation and service, and full fleet management for companies. Everything is agreed first, with a clear report before and after the work.

We work honestly. We explain every step taken on your car.
Auto Gas Gaga opened in Banja Luka in 1996 with one simple idea: work honestly and explain to every driver exactly what is being done on their car. Thirty years on, mechanics is still our core trade. We grew LPG alongside it from day one, and over the last two decades we have taken on full responsibility for company fleets across the region. Active experience on thousands of vehicles means we open the experience first, the catalogue second.
What work looks like in our workshop.
Thirty years, same routine: a clear agreement up front, honest work in the shop, a clear report at the end.
Mechanics, diagnostics, LPG
Mechanics is our core trade, from minor and major services to serious work on engines, gearboxes and suspension. On top of that we handle full diagnostics and LPG: installation, service, tuning. STAG, LPG-tech and Zavoli are our main systems, and anything else commonly found in BiH we service and tune.
How we treat customers
Every car that comes into the workshop is treated as if it were our own. We clearly say what the problem is, what is urgent, what can wait. The price is agreed up front, before any tool touches the vehicle.
People and companies come back
Private clients recommend us to family, friends and colleagues. Companies plan their fleet around us because they know the price before the car even comes in. That is how we have grown for thirty years without a single advertisement.

A fleet we manage with you.
For two decades we have been running company fleets in Banja Luka and the region. You get one contact, one contract and one budget, and we cover everything around the vehicles: mechanics, urgent interventions, registration, insurance, fuel and fines. The bulk of the work happens in our shop, and specialised jobs go to our vetted partner network where your vehicle gets a priority slot at the regular rate. Your team gets back the hours each week that would otherwise go on coordinating mechanics.
Fleet management software, free for our partners.
Companies that service with us get serious fleet management software at no extra cost. Tools at this level are expensive on the open market; with us they are part of the deal because we earn from working on the vehicles, not from licensing software.
A vetted partner network.
Bodywork, tyre service and specialised electronic work go to partners we have worked with for years. The vehicle arrives with our recommendation - in practice that means a priority slot at the regular price, with no markup from us. We follow the job through to the end, and the whole cost lands on a single invoice at month end.
See what is happening on your car, while it is happening.
Every customer who services with us gets their own e-service book. Full vehicle history in one click, every mechanic note, every invoice. And the job status in real time, so you do not have to call the workshop to ask where things stand.
A report after the inspection, on the channel you prefer.
After the initial inspection you get a report on WhatsApp or SMS, and a phone call when needed. A clear breakdown of what was found, what is urgent and what can wait, with a price for each item. You confirm what you want done now and what to defer. Nothing is touched without your approval.

Thirty years in numbers.
We do not track statistics, we track the people and companies who come back to us. This is what we know for sure.
