According to Bars Product, this is compatible with all engines and engine oils. **Q: Can you use this with synthetic oils** A: Yes, I have used it with synthetic oil with no issues. **Q: What it does with my other gasket that has not have a leak?** A: If I'm understanding your question correctly.... you would like to know what effect this has on gaskets that are not leaking? The answer is nothing..... Thank you Eric **Q: Is this safe to use with other gas additives such as seafoam, lucas?** A: Yes there is no problem. This gets poured into your oil crankcase not into your gasoline. Seafoam usually gets poured into your gas tank to clean injectors and cylinder walls sometimes you can put it in the crankcase just about 4 oz to clean junk this does not stop any leaks usually done 100 or 200 mi before an oil change. Lucas has many products some that are injector cleaners that go into the fuel tank some that are oil stabilizers or stop leaks or friction additives that go into your oil crankcase you can have Lucas oil additive/stop leak and bars leak in your oil crankcase they don't interfere with one another ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quick delivery *by D***U on 17 November 2023* Perfect ### ⭐⭐⭐ Didn't stop the leak... *by A***H on 28 September 2022* Didn't stop the leak for me, but for sure it got better....I was told by the mechanic that with the next oil change I'll have to add another bottle and the leak will stop. ### ⭐ NOT WORKING *by P***Y on 12 December 2020* NOT WORKING ## Frequently Bought Together - Bar's Leaks Rear Main Seal Repair, 16.9 oz - Bar's Leaks OS-1 Oil Seal Engine Oil Burning and Leak Repair, 16.9 oz. - Bar's Leaks 1420 Transmission Stop Leak - 11 oz. , Grey --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/257815528-bars-leaks-concentrtd-rear-main-seal](https://www.desertcart.sn/products/257815528-bars-leaks-concentrtd-rear-main-seal) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-04-22*
