Most Samurai owners service their cars themselves. I used to do that but now I'm in my early 80s there are some things that I just don't want to do anymore. To my surprise, my Suzuki recently failed California's smog test. It's getting harder to find a garage that is willing to service that Hitachi ECM carburetor. I previously had bought some products from Petrol Works and was happy with what they recommended and provided. In late 2025 while towing the Samurai through West Texas its transmission failed and locked up despite my following the owners manual instructions carefully. I took it to Petro Works and had them replace the transmission, install a driveshaft disconnect system, and an old man emu set of springs. I was delighted with how the Samurai handled after that. So after the smog test failure I decided to return to Petro Works even though it meant 1000 mile round-trip from my house in Northern California. They rebuilt the carburetor, including new, micro switches and rebuilt the mixture control solenoid. The Samurai now runs, performs and handles better than it ever has in the 10 years that I have owned it. I feel that it was certainly worth my time and money to have my RV Toad in the hands of honest, experienced technicians. read more

My Dad passed on his Suzuki Samurai to me, and asked me to fix it up and sell it. I know a little about trucks, but little to nothing about the Sami, so I was pleased to find a local "expert" in Bonsall. They checked over the car, found and fixed a few minor issues, had it smogged for me, and made some suggestions. Took a few days, I wasn't in a hurry, and when I got it back it was running great and smelling a lot better (new distributor and new catalytic). Best of all, after I gave it a good cleaning, I was able to sell it quickly, and I passed on the info to the new owner. (I would have kept it but it was just too small for me!). Thanks again, I appreciate your help! read more

Sad to say, Petroworks never ever wanted to fix my transmission which they rebuilt and left it a mess. Already went to two transmission businesses for an assessment, both tell me the synchros are bad. Petroworks ruined my transmission and they adamantly denied responsibility. Same with the radiator they installed, they installed a FI 1.6 engine conversion and aside from ruining my transmission they did something wrong with their radiator / cooling system which they also installed together with the conversion. The radiators keep cracking one after the other after about 300 miles of driving. Terrible experience. Spent a lot of money for this conversion and ended up with an unreliable vehicle that cracks radiators every 300 miles and has a broken transmission. No ethics. No morals. Sabe yourselves headaches and costly tows , fo somewhere else read more

When petroworks put in a new engine, they did not bother to put on a new Timing Belt, rather they took the old Timing Belt off my old engine and put it on the new engine Date Code Proves this which is on the belt.....then they did the same with the water pump and the oil pump. So they could sell the new parts on line. Crooks The water pump gave out and it is suppose to be a new engine. Also, I have noticed, screws and bolts missing in certain areas of places they worked....Greasy finger prints all over the hood and steering wheel. Just sloppy work with low integrity. read more

I just can't say enough about Gary and Petroworks. I have a 1987 samurai and it needed some work. What kind I wasn't sure. Gary fixed it up and now it's running like a champ. It turned out to be a bunch of little things and not what one place I went to first said was wrong. I'm so happy with Gary and his crew at Petroworks. I can't say enough how honest and the quality of work you'll get when you use Petroworks. Thank You Gary and crew. Mark Colonna read more

Petroworks deals with Suzuki's, that's what they do, it's their "niche." I had been looking to buy a Suzuki Samurai for many months, to use as a "toad" (tow behind RV) vehicle and as a daily driver for my short local drives. As I did my research and shopping on line (craigslist & ebay), I kept running across the name, "Petroworks," as a a highly reputable shop for stock and upgrade mechanical work, as well as the seller of custom fabricated parts that they have machined for drive lines, suspensions, transmissions, etc, etc. Also as a vendor for many after market as well as OEM parts. Finally, I called them just to see if maybe they had a vehicle for sale, or a lead on a good vehicle. They didn't. Months went by as I test drove several, almost made 2 purchases (1 an ebay scam, the other wouldn't pass smog). Finally I called Petroworks again and this time Dave was aware of a very clean, almost stock, '88JX that wasn't for sale yet, but the owner was about to list it. Dave got me in contact with the owner, and we did the transaction. It was a great buy, as I've seen many rigs of similar condition listed for around $2000. more. However it was an Arizona vehicle and not CARB compliant, with a great CV carburetor on it and the associated non-stock manifold that is a Petroworks product. Petroworks had done the wrenching. Gary at Petroworks assured me he could do the carburetor work so I could get it CA smogged. He said he's buy back the custom manifold and the CV carburetor against the cost of the work. I also needed to have tow bar mount plates installed and tow lights hard wired in. I opted to have Gary make an easy customization on the door hinges to make them easily removable. I've seen custom billet hinges on ebay that make the doors removable for about $300. Gary customized my stock hinges for a small fraction of that. Being new to the Suzuki Samurai world, and new to flat towing, I had a lot of questions for Gary about various after market parts, upgrades, and customizations. From our initial contact and throughout our business, Gary has insisted that I not buy things, or make upgrades that I don't really need. He says things like, "You don't need that, and here's why..." Or, "I can show you a real easy way to do that yourself, unless you really want to spend your money." This is almost unheard of customer service policy in todays market. And it goes a long way in explaining the references to, and positive comments about Petroworks I have seen on sites like ebay, craigslist, izook, zukiworld, and zukinovations. Gary ended up crediting me back more than I expected for the CV and manifold. He not only made it CARB compliant, but he got it smogged for me too! I had not asked him to do that, but he said he was "covering his own ass" too by doing that, and I of course paid for it as I had to do it anyways. Last thing I want to mention is about the front bumper. In doing my research for tow bar mount plates, I was trying to identify the custom front winch bumper because I figured the manufacture may offer a mount. I decided it looked most like the calmini bumper. But it turned out that Petroworks had custom fabbed it in their shop. It's a piece of art work as far as welding and fabrication goes. I had a quote from Temecula RV of between $1600 and $2200 for front mount plates and tow bar. Gary set me up tow bar equipped and lights for less than 20% of that quote. It's not real fancy, but it's super clean work, it's bullet proof strong, and he didn't sell me crap that I didn't need. I will never go anywhere else for my after market parts and wrenching. If Petroworks doesn't sell it, I probably don't need it. George Atwood Temecula CA. read more

I found Petroworks online when searching for parts immediately after I purchased a 89' samurai. The vehicle had some issues passing smog when I got it so I called with a few questions. The owner answered, gave me some tips, and it passed the smog inspection. Since then I've ordered a few parts and most recently brought in my Sammy for some much needed love. They upgraded the front axle shafts, added side gears, welded on an axle truss, rebuilt the carburetor and got it smog checked. I've put 1500 miles on since then as a daily commute and it runs great. They perform their own machine work, rebuild parts in house, have a few long term employees, and have great customer service. If you have an issue with an older Suzuki vehicle in Southern California I recommend making an appointment for service. I towed mine 75 miles for the work and would do it again to know it's done right. read more
