SynGas markets an OBD2 fuel-saving car accessory sold online through sites such as getsyngas.com, promoting improved fuel economy and engine performance for passenger vehicles.
SynGas is an automotive accessories brand that sells a plug‑in “OBD fuel saver” device. The product is marketed as a small module that connects to a vehicle’s OBD2 (on‑board diagnostics) port and claims to optimize engine performance, reduce fuel consumption, and lower emissions over time. It is sold primarily through direct‑to‑consumer websites such as getsyngas.com and related SynGas‑branded landing pages targeting drivers looking to cut fuel costs and improve mileage.([syngasobd.com](https://syngasobd.com/?utm_source=openai))
A charge labeled “CART-DEALSHOPO” has been reported by customers as corresponding to an order placed with SynGas via the getsyngas.com checkout flow, where the card description did not clearly match the brand name. In at least one detailed Trustpilot review, a user describes purchasing a SynGas OBD fuel saver, then seeing “CART-DEALSHOPO” on their credit card statement for that transaction, along with unexpected extra items and difficulty cancelling immediately after ordering.([trustpilot.com](https://www.trustpilot.com/review/getsyngas.com?page=9&utm_source=openai)) Because of this, if you recently ordered a SynGas fuel‑saving device or related add‑ons, this merchant descriptor likely reflects that online purchase.
If you have questions about a SynGas‑related charge, start by searching your email for order confirmations from getsyngas.com or other SynGas domains, and compare the billed amount and date to what appears on your card. You can contact SynGas customer support using the email address listed on their site (for example, support@getsyngas.com) or via any support links provided in your confirmation messages or on the SynGas website.([trustpilot.com](https://www.trustpilot.com/review/getsyngas.com?page=9&utm_source=openai)) If you believe extra items were added, or you did not intend to complete the order, contact the company promptly to request cancellation or a refund, and if that fails or the charge appears fraudulent, work with your card issuer to dispute the transaction and block further charges.

What products does SynGas typically charge for, and what are common order amounts?
SynGas usually charges for its OBD2 fuel saver device, often sold in single‑unit and multi‑unit bundles, sometimes with add‑on items such as extended warranties or additional accessories. Customer reviews mention that the checkout flow can present multiple upsell offers, which may result in higher‑than‑expected totals or multiple items on one order. Review your online invoice to see exactly how many units and add‑ons were billed.([trustpilot.com](https://www.trustpilot.com/review/getsyngas.com?page=9&utm_source=openai))
I only meant to buy one SynGas device but see extra items on my order. How do I fix this?
Some reviewers report that they intended to purchase a single SynGas device but ended up with extra units or add‑on products added during the upsell steps in checkout. If you see additional items on your confirmation or statement, contact SynGas support immediately with your order number and request that the unwanted items be removed or refunded. Acting quickly improves your chances of cancellation before shipment or of being granted a return authorization.([trustpilot.com](https://www.trustpilot.com/review/getsyngas.com?page=9&utm_source=openai))
How can I cancel a SynGas order before it ships?
To attempt cancellation, locate your order confirmation from getsyngas.com, then reply directly or email their support address (such as support@getsyngas.com) with your full name, order number, and a clear request to cancel. Some customers report being told their orders had already been packed, so cancellation may not always be possible; in that case, ask for written instructions on how to refuse delivery or return the items under their stated return policy.([trustpilot.com](https://www.trustpilot.com/review/getsyngas.com?page=9&utm_source=openai))
What is SynGas’s refund or return policy if I’m unhappy with the device or the charges?
According to customer accounts, SynGas mentions a return window (often around 30 days) during which you can request an authorization to return items for a refund, but you may be required to pay return shipping yourself—even for items you believe you didn’t intend to order.([trustpilot.com](https://www.trustpilot.com/review/getsyngas.com?page=9&utm_source=openai)) Always check the current Terms & Conditions and refund policy on getsyngas.com, request a written return authorization, and keep tracking and proof of delivery when sending anything back.
How do I contact SynGas about a billing problem with a CART-DEALSHOPO charge?
Use the contact details listed on the SynGas/getsyngas.com site, such as their support email address and any contact form provided.([trustpilot.com](https://www.trustpilot.com/review/getsyngas.com?page=9&utm_source=openai)) Include your order number, the date and amount of the charge, and screenshots of your statement showing “CART-DEALSHOPO.” If you cannot reach them or they refuse to correct an error, you can escalate the issue to your card issuer and file a charge dispute.
Is the SynGas OBD fuel saver a subscription or a one-time purchase?
SynGas is generally marketed as a one‑time purchase for a physical OBD2 device rather than as a recurring subscription.([syngasobd.com](https://syngasobd.com/?utm_source=openai)) However, extra products or warranties may be bundled in at checkout, so carefully review your confirmation email and card statements over the next few months to ensure no unexpected recurring charges appear.
What should I do if I don’t recognize the CART-DEALSHOPO charge at all?
First, search your email and browser history for SynGas or getsyngas.com in case someone in your household ordered the product. If no one recognizes the transaction and you find no corresponding order, contact your bank or card issuer right away to report an unrecognized or potentially fraudulent charge. They can block your card, investigate the merchant, and help you dispute the transaction if necessary.
