EDGE Extended Performance 5W-30 Advanced Full Synthetic Motor Oil, 5 Quarts, Pack of 3

Can't beat this for high quality oil. Price great.

Very high quality

I may be bias, but I've been running some formula of Castrol in every single one of my vehicles since I could drive. However, I did go through a nearly decade long phase of running every shelf oil imaginable, and this generation of Castrol Edge takes the cake. First and foremost, I run the EP platform as I like the overkill on my rig because not only do I live in AZ, but I also abuse the hell out of my cars, and when I say abuse, I mean that they are my money makers and my daily. I keep to the 5k intervals on my Tundra because it takes 6 months anyway, but in that time, I tow a lot, short trip it like crazy, floor it on the interstate or to get around those pesky snowbirds that flood our roads, we take 5-6 long trips every year through various terrain and mountainous switchbacks, 2-3 camping trips, off road, you name it, this trucks done it. Anyway, the performance from Castrol is the most consistent I've ever seen out of any synthetic in the last 8 years. ESPECIALLY For the price point. I've run AMSOIL EP and that was an astounding oil but too rich for my blood and since I change the oil at 5k anyway, I hardly see the value. As this Gold bottle Castrol AMSOIL won't test against. But they'll test against the standard black one, on their signature series, and it comes darn close. Castrol is best for its heat retention and shear stability. And I think that's where this performance factor comes into play. Mobil1 and Valvoline made me think my rings were sticking and I was having consumption issues, nope, not a drop with Castrol, not on my ford, not on my Honda, my Toyota, any subaru, or my Chevy. M1 would shear to a 5w20 to by 1000 miles and I'd be 1/2 to 1 quart down by 2k. Valvoline was better but still would start to lag the engine a little when stressed, pressures would dip enough for the engine to really start to work to keep itself cool. I'd like to point out, Castrol GTX, EDGE and EDGE EP are the only shelf oils that read "exceeds API standards" rather than "meets or exceeds". Which some would brush off as legal jargain and marketing, which would be true, but if you dive deeper into how oil batches are manufactured, then it suggests more consistency in their manufacturing. Especially when you have an ACEA rated oil in a U.S. Cafe spec. That's a pretty robust concoction. All in all take it with a grain of salt, understand there's no vehicle in the world that operates under "normal" driving conditions and use quality, oil and filters you trust on a regular "severe" maintenance schedule, and you'll be fit as a fiddle. But this stuff has carried my truck and my family all over the US for the past 80k with consistent performance throughout the entire interval.

Great product, I am please with my purchase and the flawless delivery by www.amazon.com!

Worked out well but the price skyrockets after first purchase. back to the 5 qt bottle

Damn good stuff! Very pleased with price and product quality! Castrol is great oil!

Compre 3 galones y solo me llegaron 2 Tuve que llamar a servicio al cliente y al final me devolvieron el dinero de un gallon Buen producto pero mala entrega.

One of the best oil

Excelente aceite, a un año que lo compre y el motor de mi carro esta en perfecto estado, volveré a comprar otro hoy 19/11/2025

Product lives up to the reputation and works as designed.

When I used it for the first time i was happy bit now after 8000km i think its losing viscosity and my engine running hard and the oil is really drity it was really bad experience am sorry for my car not

The oil seems great and it was delivered faster than I expected it but as far as the quality goes I’ll have to wait till the next service and see for myself how good this oil really is

El aceite es muy bueno, lo mejor del mercado
