high quality FULL synthetic oil

Trusted Castrol quality at a good ptice

I've used the Castrol synthetic oil during oil changes for years among other brands. I have nevee had any issues. The oil protects as needed and I have never noticed any odd engine noises, no decrease in fuel economy or had any engine issues due to it's use. The key I believe is proper and prompt maintenance using good products. So far, this motor oil has never let me down

Perfect oil for my old truck!

AAA_as described, fast delivery, well protected_AAA

Many years ago one of my buddies who builds off road race trucks said to just stick with Castrol so I always have. It has always worked so thats what I use and will continue to unless they mess with their oils. If it ain't broke don't fix it.

I give it a five star because it’s engine oil and it works in my car, but my five-star rating doesn’t mean I’m an engine oil expert or that this oil is better than any other oil brand. I have previously been told that the best engine oil brand is ANSOIL, which if going by its price, it must be a superior oil. As I was told, ANSOIL doesn’t have any wax substances, which, supposedly, can be problematic for some engines. Anyways, I purchased this oil for four main reasons; it’s synthetic and superior to most petroleum-based oil. I can get it a lower price here at Amazon than on any other local store. It arrives at my home free of shipping charges…well somewhat free since I must pay for my Prime subscription…I guess nothing is really free. But the main reason is because I had changed the oil on my 2013 Mazda CX9 a few weeks before and then realized I had used the wrong oil specifications. The 2013 Mazda CX9 calls for 5W-20 oil and I had used 10W-20 instead. Must mechanics I consulted with said it wasn’t a big deal, while online forums were not cleared about the subject. I didn’t think it was going to cause problems either but wasn’t completely sure. So, I reasoned, it’s my car, I’ve been taking good care of it and it looks and run like new. So, I had to decide on whether to spend another $24.67 and have a piece of mind or not replaced the oil and ran into many sleepless nights wondering if not changing the oil was the right choice. So, I replaced it, I’m short of $24.67, but having piece of mind is priceless. By the way, I’ve been using Castrol oil on my cars, for the most part, since I purchased a new 1986 Dodge Daytona…it was a nice looking car, but poorly made.

Solicito factura, buen producto

Es bueno y según sus especificaciones es para alto kilometraje sin cambio de viscosidad

Calidad y precio

Me llegó en buenas condiciones y cumple con su función .

Hace seis meses use este aceite para la afinacion. Le volvi a cambiar el aceite seis meses despues y salio horrible. Le pongo 3 estrellas porque si lubrica eso esta claro pero deja una capa mineral chiclosa y muy viscosa. Me tapo valvulas y subio el consumo de gasolina y la foto izquiera era antes y la derecha es el despues. Mis valvulas estaban limpias hasta que use este aceite genero una capa de carbonilla. Le pronostico fallas mayores en un par de años par andar usando este aceite. Mi opinion profesional es que no usen aceites que no sean de la marca que indique su manual de prpietario. Tenia años usando motorcraft y nunca tuve problema hasta que decidi cambiar por la idea de menor desgaste y probar nueva marca.
