I'm due for my 5th service next week and was wondering if anyone could share their experiences regarding the cost-effectiveness of these TL free services compared to third-party service stations. I'm particularly interested in factors such as the quality of service, additional charges, and overall satisfaction. Have any of you found that the free services offered by TL are more cost-effective in the long run, or do third-party service stations offer better value for money?
