Its ester/PAO formula ensures superior cleanliness and extended drain intervals, making it a top choice for discerning drivers and performance enthusiasts alike. ## Description Fully-synthetic ester formula for passenger cars, light trucks, performance vehicles and marine applications. Excellent wear protection and friction reduction across a wide range of operating conditions. High detergency allows extended drain intervals and provides increased cleanliness. Improved fuel economy and ring seal for more power. Superior high temperature stability and oxidation resistance increases lubrication of hot metal compared to other synthetics. High natural viscosity index provides thicker oil film in bearings and cams. Less evaporation than other synthetics for improved efficiency and ring seal. All products are completely compatible with other conventional and synthetic motor oils. Review: This is the best oil I could find for my specific application. I have a modified and tuned BMW 335d (diesel), that is putting out approximately 600 lb ft of torque at the rear wheels, and just under 375 whp. Given the near 40% increase in torque (and the fact emissions controls were no longer an impediment to the type of lubricants I could use), and with no modification to the lubrication system - I needed to find a suitable oil with a higher HTHS value to protect the lower end components from excessive and accelerated wear - while not going so out of spec in viscosity that I compromised other engine components due to reduced flow from increasing viscosity too much. BMW specifies from 5W30 to 5W40 for the M57 engine. The OEM spec oil is approximately a 3.2-3.4 HTHS viscosity (CP) oil. I searched all available oils in the specified range from every manufacturer for an oil with a notably higher HTHS viscosity and the only company that produces an in-spec oil (5W30-40) with a higher HTHS than OEM spec is Redline. This oil (High Performance 5W40) has a HTHS vis of 4.4 CP, which is a significant increase over the emissions compromised OEM synthetic oil. No other oil manufacturer comes close - not Amsoil, not Motul, not Mobil One, not Royal Purple (not that I would ever use that garbage). In fact, many of the premium brands have a slightly lower HTHS. HTHS is not the biggest selling point either - Redline oils are currently the best oils on the market, with the highest levels of ester. While it’s no longer a complete Group V synthetic (it’s technically a Group IV now based on the proportion of PAO to Ester in the blend - it is of course a true “full synthetic” oil - the ‘blend’ is the combination of synthetic base oils... PAO and Ester), it still has the highest levels of ester in any automotive oil. I also use Redline 0W40 in the winter months. The HTHS is slightly lower (4.0 CP), but still notably higher than OEM. The reduction in vibration during high load and under heavy acceleration is significant - back to stock levels... except accelerating much faster! For note. I’ve been an Amsoil dealer for over 20 years (for personal use - before the preferred customer program came about), but have noticed a disturbing trend of decreasing performance of their products since the founder passed away and his son took over. TBN, NOAK, HTHS, and other important characteristics have all declined to the point their engine oils are really not any better than Mobil One - yet they still charge a premium price. I am not renewing my dealership this year and have converted all of my cars to Redline engine oils and fuel treatments. I still use Amsoil gear and transmission fluids at this point, but will be monitoring their specs for the kind of decline other Amsoil products have suffered. One last note: I contacted Amsoil tech services first when considering my options for a more robust oil. I explained the modifications made to the car and asked what oils they would recommend in the Amsoil product line. To my dismay - they would only recommend their OEM equivalent oil - which actually has a slightly lower HTHS than the BMW spec OEM. They stated they could not make recommendations for modified vehicles. Clearly they do not support the high performance aftermarket any longer. Redline tech services took the information I provided and recommend three of their oils depending on the type of driving. They of course stated that since the car was modified, no company would warranty an engine against oil related failures - but noted Redline Oils have never been the source of any known oil-related engine failure. Redline still supports modders and rodders! Review: Pues la entrega segun previsto. Y que puedo opinar sobre este aceite: este es el top de los aceites 5w40 ,a día de hoy no ai nada que lo supere,según prueba de laboratorio. De aquí ya no ai nada ,esto es lo más. Es un aceite full saps,osea no vale para filtro de partículas ,aunque es bajo en cenizas,supera un poco la norma C3 pero bueno ,avra que probar. Sin duda esto es la crema de los aceites. ## Features - Harmful to aquatic life with long lasting effects. - 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 500.00/501.01/ 502.00/505.00/505.01, BMW LL-01, water-cooled Porsche A40 and Mercedes-Benz 229.1/229.3/229.5 applications, recommended for API SN/SM/SL/CF and ACEA A3/B3/B4 - WHY RED LINE - Established in 1979, Red Line Products perform & protect better than any on the market.

I use it in my 1,000hp LSA Yukon Denali. Check around for price though, I usually pay around $130 for a case of 12. Check 3rd party sellers on Amazon or use Autoplicity **Q: is this oil non-detergent?** A: Redline oils are known to have a high amount of detergents & cleaning agents in them, along with several other beneficial additives as well. The end result of long-term use of Redline motor oils according to many of the oil-analysis I've seen is a very clean engine with low levels of wear & tear (assuming the engine hasn't been abused and regular oil change intervals are being followed). I've been using Redline 5W-30 in my 2014 Infiniti Q50 3.7 for the last 3 1/2 years and the engine still runs & performs like it did when it was brand new. According to consumer reviews, oil analysis, and some of the other data out there it's definitely one of the best motor oils that money can buy. **Q: Which red line is better for audi a6 2000 biturbo gasoline engine ?** A: Go for the temperature range for the climate zone you are in. Thinner oils for the winter and all that. For example, a 5W-40 this time of year is good for about anywhere. Where I was a year ago, 0W-40 would be best for New England in the winter. I have also used 15W-40 in the summer in Phoenix. HTH, & Cheers! **Q: Why does the origin say china? I thought redline was made in California.** A: That's b/c Amazon generates these ads when the product is already listed by another vendor, we can't control this. It is in fact made in CA. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***T on 4 July 2020* This is the best oil I could find for my specific application.

There’s a near instant difference between this and the common oils everyone uses. The motor immediately sounded better on both warm and cold starts,as well as an apparent increase in gas mileage by around 20% due to in the increase in lubrication. I would only put this in a car that’s either high end or you’re a person with a heavy foot or both. It’s very expensive but it’s worth the cost. ## Frequently Bought Together - Red Line 15405 SAE 5W40 Fully Synthetic Motor Oil - 1 Gallon - Red Line 60103 SI-1 Complete Fuel System Cleaner - 15 Ounce (2 Pack) - LIQUI MOLY Oil Additive Cera Tec 20002 Ceramic Wear & Tear Protection for Petrol & Diesel Engines Smoother Engine Performance, Less Friction & Lower Fuel Consumption 300 ml --- ## 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.vn/products/456928813-15405-sae-5w40-fully-synthetic-motor-oil-1-gallon](https://www.desertcart.vn/products/456928813-15405-sae-5w40-fully-synthetic-motor-oil-1-gallon) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
