5.0 out of 5 stars Helps Reduce Carbon Buildup on the Valves and Reduces Sludge Formation
Reviewed in the United States on July 20, 2020

I've delayed reviewing this oil because it takes months or more to be able to say anything worth saying about a motor oil. What I can say about this one is that it definitely reduces carbon buildup on the intake valves of my car's GDI engine.What it all comes down to in a nutshell is that GDI engines don't get the fuel wash effect of gasoline passing over the intake valves like carbureted and port fuel-injected engines do. That means that the hydrocarbon vapors coming from the PCV systems form deposits on the intake valves that never get washed off.Oils like this one are engineered to be less volatile at operating temperatures, which reduces the vapors coming through the PCV system.One of the ways I know this oil is producing less vapor is that the oil level hasn't budged since the last time I checked it. I never considered my car to be an "oil burner;" but this time around, after two oil changes using this oil (with induction system cleanings before each oil change), there's no measurable loss at all.No loss of oil in the crankcase means little or no loss to vapor in the PCV system, which in turn means little or no buildup on the valves.If your car has a GDI or T/GDI engine, therefore, I can recommend this oil as a good choice. There are others, of course; but this is the one we're talking about now, and it's a good one.RichardEDIT: I'm updating this review with borescope video of the head under the valve cover. What I was looking for sludge to decide if it was time for a flush after 50K miles. No flush needed. In fact, I was pretty amazed at how clean it was under there.So not only does this oil reduce carbon in the induction system, but it has excellent detergency as well.

Was changing oil today, but filter was stuck. Finishing up tomorrow.

Have used before, gets great in between changes mileage on v8 high mile van. 4-5 months, little over 70 mile daily driver vehicle. Stops ticking of valves, but it says 200k between changes in barely at 30k; BUT DON'T LIKE OIL TO GET REALLY DARK.

Don’t get skimpy when it comes to motor oil, cheap help towards increasing vehicle longevity, and mileage. In addition, since you would be changing regular oil over 3 times as often as this 10K oil, it’s actually the less expensive alternative in the long run.

I have used Mobil 1, Valvoline and other full synthetic oil but none is as smooth as Castrol edge full synthetic. Even after 3500 miles the oil still has brownish tint and no sign of engine struggle. I highly recommend this product.

I use it in my 2018 GMC Terrain 1.6L Turbo Diesel. It calls for 5w30 Dexos 2 motor oil. Its not readily available where I live so I order it online. You have to be careful of oil because Dexos 1 Gen 2 is readily available and easily confused but it is not good with DPF. I like Castrol oil just because I have used it a lot. I realize it is probably all marketing but what the heck it makes me feel good.

My oil burning Audi drinks this like water, and this is the least expensive place to find alongside convenience. Designed for the little German nightmare to eat and ruin the environment whilst at the same time providing an insanely satisfying driving experience.

Thank you for the magical synthetic dinosaur juice.

No complaints for a full synthetic high mileage oil esp. at this price point. Combined with a Mobil 1 filter, I'm confident my 2005 vehicle will keep on going.

It's been a year since I put this in my 2003 VW Passat W8 and I looked at last week and it's just as clean as the day I put it in, (very very close). It's actually clearer now than other oils are brand new. It was a bargain last year. I guess it was on sale. I don't know how to predict those. I will say that if you bring your own oil and filter, the cost to change your oil is very pleasant. You've paid in advance, so it's still expensive to have a car. It's just great that you can know the quality of what's going in your car. The clarity may have been partly due to the Bosch oil filter. It's specs are much better than other brands. install and you know the filter is the best. Bosch cabin filters are awesome too. I'd recommend buying oil filters and cabin filters in quantity so you don't have to go to the trouble of buying them. Just get the oil. (Does oil store well? I began to doubt that. So I'm not recommending that.) I am here to buy it again, so I'd recommend doing these things too. If you take your car to an oil change place, be sure you pick out quality oil, oil filter and cabin filter beforehand, and bring them when you go. It's your assurance that your doing the best you can for your car, and not just leaving it up to the Quicky Change place's choices for their benefit. And yes, of course it's great to see that the oil change will be so cheap by comparison to buying their oil at the same time. It may be me tricking myself by spreading out the costs, call it what you will. It's still nice to know everything is my choosing and the oil change charge will be cheap, since you're bringing your own stuff. It's like a reward for taking the time and trouble to shop for what you think is best. You might change your mind later. Who knows? I liked this oil and I liked the Bosch filters I bought too. This oil seems like it's smoother at high RPM, over 6,000. That's where I noticed the engine sounding like it's "taking it easy". Before, I really avoided driving in that range, but it feels more comfortable. That's got to be a good sign for the oil. In fact, when you stomp on the gas, the car overreacts and downshifts twice, which lowers the power to the wheels. Best to just ease it up quickly, no stomp. But I was testing the car and noticed that it no longer slows the car when doing this. It's just the beginning of a more normal acceleration. That's better oil. Anyway, your performance may vary but I don't think you can go wrong with this oil. It's the best stuff I've ever had in any of the cars I've owned. That says a lot.

A los 2,000 km del cambio de aceite el motor comenzó a tener un mal sonido por lo que nuevamente realice el cambio pero por un liqui moly y se soluciono, este castrol me parece de mala calidad, dudo sea original y la botella no tiene ningún holograma de autenticidad

Este aceite lo vengo usando desde nuevo mi vehículo. Lo manejo en la plataforma de Uber. Todos los días hago un promedio de 300 o 400 kilómetros. Y el motor está funcionando en perfecto estado. Cambio de aceite cada 15000 kilómetros, tas vez da más con algún filtro de alto rendimiento. Pero no son fáciles de encontrar. Mi auto lleva 300,000 kilómetros y amplia espectativa de alta duración.

El producto es muy bueno ya que cuenta con el respaldo de una marca de lubricante de clase mundial, en este caso muy adecuado para los motores de alto kilometraje usados en condiciones demandantes (climas extremos, fuera de carretera, trafico denso en ciudad, etc.). Por ello ha sido siempre mi recomendacion a mis clientes con servicios desde que sus vehiculos dejan de ser llevados a sus servicios de agencias cuando concluyen sus garantias.
