Established in early 2000, our diesel repair center has grown from a tiny one-man show into a thriving national operation
In the late '70s, John Brennan discovered his passion and talent for innovative diesel performance injection systems and repairing diesel pumps, while under the watchful eye of Tom Cooney
After honing his diesel repair skills, John set up his small repair shop at his house. Portlaoise Diesel Injection was open for business, though business wasn't exactly booming John sweated out the rough in the early years the only way he saw fit—by establishing innovative diesel performance that saves customers money over the long haul and by providing dedicated, honest service.
Remaining true to those core values to this day. Portlaoise Diesel Injection has earned its place as a leader in the Irish diesel market and later looked to expand on that success.
The company expanded its workforce to fifteen over the years and in 2012 they moved to a larger premises where business continued to grow. John now had a garage running full time alongside his repair workshop.
In January 2022 John leased the garage aspect of the business to Laois Auto Care to let John focus on his real passion of repairing the pumps and injectors.
In March 2023 John retired and Portlaoise Diesel Ltd owned and run by Eugene Hearns has taken over.
