Oil doesn't make your car run good, it doesn't make it more powerful, it doesn't make it idle smoother. It can make some noises go away, but that's almost always a sign that the oil that was in it before was worn out or not correct for the application, OR that something is already worn out, and the new oil is covering that up (not fixing it). What oil does is keep your engine from wearing out. It cannot make your engine better, it only stops it from getting worse. How good of oil you use and how often you change it will determine how long it's able to do that. So my review leads to here, I'm not a chemical lab, I can't show you how good the oil *is*, but I can describe how it has worked for me. I've got a few cars, and I take care of them all a little different. My every day car that gets all the miles and maintenance is a little 2.0L Suzuki inline 4. As of this review the car has right at 200,000 miles, most driven moderately, some driven pretty spiritedly 😉 I've only used redline in the engine since I took ownership and in my opinion (20 years full time shop mechanic) it runs exactly as I would expect a new one to. No smoke, no ticks, no knocks, no rattles, no VVT errors, valve lash stays in spec with no adjustment every time I check. Those are the things oil is meant to protect against, and in my 200,000mi real world experiment I would say it is protecting against them very well. It is pricey compared to most other options, but if you're keeping it for the long run, quality oil changed on time is the cheapest and most effective warranty you can buy. Review: Best motor oil that money can buy, without question... - This is without a doubt the best motor oil on the market. Over the years I've used various different brands of synthetic including Mobil 1, Castrol Syntec, Pennzoil Platinum, & Liqui Moly just to name a few, and Redline is the only brand I've tried that made the VQ37VHR motor in my Infiniti Q50 run smoother and quieter. I went from Mobil 1 Extended Performance to Redline and I immediately noticed smoother and quieter acceleration, and during idle the engine is barely audible. I have also noticed a slight improvement in fuel economy as well. It's hard to believe that going from one motor oil to another in the same viscosity could make any noticeable difference in engine operation but in my case it definitely did because the engine really does feel happier and healthier with the Redline oil. There's also a lot of good information out there that shows Redline oil can actually reduce oil temperatures as well as keep your engine cleaner. And the added detergents, ZDDP, molybdenum and ester molecules can really help to reduce friction & engine wear and keep the engine clean over time. But the synthetic ester base is what really makes the difference between Redline and all of the other motor oils out there, and it's what also accounts for the increase in price. The only downside is it's expensive when compared to most of the other synthetic brands out there, but this is an Ester-based Group V synthetic motor oil that is aviation grade, and you get what you pay for. For me it's worth spending the extra $15 per oil change and I'm definitely not planning on switching to any other motor oil again as long as the Redline continues to perform this good. ## Features - FULL-SYNTHETIC - ester/PAO formula for passenger cars, light trucks, performance vehicles and marine applications - HIGH DETERGENCY - allows extended drain intervals and provides increased cleanliness, Improved fuel economy and ring seal for more power - BLENDED WITH - polyol ester/PAO base stocks that feature natural multi-grade properties, avoiding unnecessary additives that hinder lubricity - POPULAR PERFORMANCE OIL FOR - VW/Audi 502.00/503.01/505.01-99, BMW LL-01 and Ford WSS-M2C946-A, API SN/SM/SL/SJ/SH/SG/CF and ACEA A3/B3/B4, GM dexos1 (GM-LL-A-025, GM6094M and GM4718M) and BMW LL-01 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004BONVB6 | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #42,339 in Automotive ( See Top 100 in Automotive ) #388 in Motor Oils | | Brand | Red Line | | Brand Name | Red Line | | Compatible with Vehicle Type | Car | | Container Type | Bottle | | Customer Reviews | 4.8 out of 5 stars 569 Reviews | | Global Trade Identification Number | 00083522153058 | | Item Weight | 3.2 Kilograms | | Liquid Volume | 3.79 Liters | | Manufacturer | Red Line | | Manufacturer Part Number | 15305 | | Model Number | 15305 | | Package Information | Bottle | | Size | 1 Gallon (128 Ounces) | | UPC | 083522153058 | | Unit Count | 128.0 Fluid Ounces | | Vehicle Service Type | Car | ## Product Details - **Brand:** Red Line - **Liquid Volume:** 3.79 Liters - **Package Information:** Bottle - **UPC:** 083522153058 - **Vehicle Service Type:** Car ## Images ![15305 SAE 5W30 Fully Synthetic Motor Oil - Gallon - Image 1](https://m.media-amazon.com/images/I/71vmS6r99OL.jpg) ## Questions & Answers **Q: I readon bobstheoil guy that this does not stand up to short trip drivng? Any thoughts?** A: This oil (Red Line 5W30 Motor Oil - Full-synthetic Ester Formula Car Engine Oil) is still one of the best oils available, and it will certainly stand up to short drives. Automobile engines, on the other hand, don’t like short drives, because it’s not enough time for the engine to warm up to proper operating temperatures. Engines don’t like to be run cold. **Q: Flash point?** A: ACEA Service Class A3 B3/B4API Service Class SN/SM/SL/CFSAE Viscosity Grade (Motor Oil) 5W30Vis @ 100°C, cSt 11.9Vis @ 40°C, cSt 71Viscosity Index 166CCS Viscosity, Poise, @ °C 60@-30Pour Point, °C -45Pour Point, °F -49NOACK Evaporation Loss,1hr @ 482°F (250°C), % 6HTHS Vis, cP @150°C, ASTM D4741 3.7 **Q: how does redline oil do in cold temperatures?. I have used mobil 1 and pennzoil synthetic but wanted to know before giving this a try** A: I have been using this oil for over 10 years. I live in the Mid-Atlantic state area. I've tried Mobil 1 and Pennzoil. Redline works better. All 3 pour the same in winter. My engines burned more oil with the other 2. Redline works well in high mileage and/or over 4 yrs old. I put about 5k miles on each of my 3 cars per year. I change the oil 1 time per year. I would rather spend a lttle more per quart and change less often. The only draw back is I found is, once you start using it you have to keep using it or you burn oil. **Q: Has anyone used this oil in an ecoboost F150 just bought a 2019 2.7 and It’s almost time for first oil change** A: redline unlike other oils it don't shear in turbos. which makes it one of the best oils to use in the ecoboost. I use it in my (f350 which is a 2010 6.4 compound turbo diesel 15w40). i also use in my 2013 (mustang 5.0 not turbo 5w50) and my wife's (2019 ecoboost 2.7 turbo 5w30) all my vehicles I have gotten new and all ran with the oil it came with for 500mile for breakin time then I went to redline. I have never had a problem with redline and all my cars but the diesel I change the oil every 10,000 miles. The truck I change every 15,000 mile and the oil looks the same as it did going in but just a little darker. I also use the full synthetic oil filter because the filter Is alot better such as wix xp.

I use it in an Audi TDI (diesel) Q5, and also in an Audi RS5 V8. Breakstone testing shows very good results. It is more expensive than other oils, but I feel it is good value for the money. The company has developed a number of products working with race teams. ## Frequently Bought Together - Red Line 15305 SAE 5W30 Fully Synthetic Motor Oil - Gallon - Red Line 15304 SAE 5W30 Fully Synthetic Motor Oil - 1 Quart - WIX (57060XP) XP Oil Filter --- ## 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.hr/products/5838978-15305-sae-5w30-fully-synthetic-motor-oil-gallon](https://www.desertcart.hr/products/5838978-15305-sae-5w30-fully-synthetic-motor-oil-gallon) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-12*
