My vehicle is 5 years old & 18500/Km I am running but after service my XYLO E-8 so really is different to everyone services results.It's totally amazing best product & I really required to everyone if you love you vehicles so you use this STP. ### ⭐⭐⭐⭐ Fine Product... *by on Reviewed in India 26 June 2016* Used in my Ford Figo but didnt see any major improvement in performance. There was bit reduction in noise but not making much of difference. Wont buy next time.Update: seen improvement in car performance after 500 KM of run. Engine is smoother, pickup is good specially at lower speed and higher gear. ### ⭐⭐⭐⭐⭐ A wonderful Diesel engine oil additive! Use with STP engine oil flush. *by on Reviewed in India 6 October 2016* Timely delivery & product as described. Thanks Amazon India.Used it in my Renault Pulse 1500 cc diesel engine at 40,000 kms.Paid service.At the beginning I used STP diesel engine oil flush.The 10,000 km. run old diesel engine oil was drained.Following this, a new diesel fuel filter was installed by the garage.Four liters of new fresh Shell engine oil was poured-in.To this was added the STP diesel engine oil additive.The engine has become unusually quite.All diesel-ness of the engine like vibration & clatter have dramatically reduced. It's subdued now.Smoothness is the word which best describes the engine performance.Pickup has increased.As the car is mostly used in the congested city, an average of 17.8 KMPL is not bad, with AC on.(A suggestion to the vendor: Please do not apply your sticker on the directions for using this top class product.) ## Frequently Bought Together - STP 65934US Diesel Oil Treatment (300 ml) - Liqui Moly (20002) Cera Tec Friction Modifier, 300 Ml - Stp Engine FlUSh 450Ml --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/261562323-stp-65934us-diesel-oil-treatment-300-ml](https://www.desertcart.tn/products/261562323-stp-65934us-diesel-oil-treatment-300-ml) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-19*
