Does it ever leak when delivered?** A: Never leaked on me **Q: Is there any different between warren's "mag1" branded oils and the oil they sell under the amazon basics brand? even the bottle look identical.** A: I've been using the Amazon Mag 1 in a 2012 Civic since new with no problems. 166000 miles on it now. **Q: Is it okay to mix this with mag1 61794 full synthetic 0w-20 (non-dexos)? i ask because i accidentally just mixed them in a new 4runner.** A: I don't know what 61794 is but it's the same weight so I don't think it's a problem. Remember that almost all "synthetic" or 'Full synthetic" oils are really not the synthetic oils that were made before 1997. Before 1997, all synthetic oils had a Polyol-ester base (real synthetic". Then Castrol came out with SynTec which is just a hydro-cracked Dino-oil with no synthetic base. So now we have two kinds of syn oil - SAE Group 3 which is 99% of Syn oil and sells for $5-6 a quart and "real" syn oil which is Group 4 and has a syn base. If you want the $10 a quart real syn oil, you need to find AMSOIL, Redline or Royal Purple which are the only Group 4 syns around. Personally, I use Mag 1 even though it's a Group 3 and change it every 5k in my 3 Priuses.Now you know more than an oil company rep knows and things that almost all the oil companies will not talk about. Don't bother calling them. Only the tech boys at Amalie have admitted all there oil is Group 3. The tech reps at the other oil companies either don't know or won't tell you. **Q: Is Mag1 0w-20 compatible to Prius C? Or Could I use this Motor oil on 2012 Prius C?????** A: I use it on a 2012 toyota camry v6 that calls for 0w-20. I wouldnt use it on any vehicle that doesnt call for 0w-20 oil but if it does it should be fine. Check your owners manual. This oil is just fine for me. --- ## 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.us/products/25054310-mag-1-20139-0w-20-full-synthetic-motor-oil-5](https://www.desertcart.us/products/25054310-mag-1-20139-0w-20-full-synthetic-motor-oil-5) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-07*
