EDGE 5W-30 LL Advanced Full Synthetic Engine Oil, 20L

I have been using Castrol EDGE 5W-30 LL in my Citroen C1 for many years now and it has become my go to choice. Despite being a small car, my C1 can be surprisingly greedy when it comes to oil consumption. I have found that this specific synthetic oil manages that appetite much better than cheaper alternatives. Why I Keep Coming Back: Engine Smoothness: Since switching to this, the engine feels noticeably smoother and quieter, especially during cold starts. Longevity: It really does seem to last. I have noticed a significant difference in how long I can go between top ups compared to budget brands. Reliability: I have purchased this many times over. While the price point is a bit higher, the peace of mind and engine health make it worth the extra investment. The 4L bottle is also a perfect size for keeping in the boot for those regular checks. If you have a car that tends to run through oil quickly, I highly recommend giving this a try. It is a premium product that delivers on its promises. Also great to have before a big journey to do a bit of a top up. It also pours really nice and I find the bottle easy to hold and pour from.

I’ve been using Castrol EDGE 5W-30 LL to top up my Seat Ibiza 1.2 Tech every 6 months, and I’ve been very happy with the results. The engine seems to run smoothly and consistently, with no issues between services. I’ve previously used the Halfords own-brand oil, but in my experience, Castrol EDGE feels like the better product. While it’s difficult to measure the difference exactly, my engine appears to run better and gives me greater confidence that it’s getting the protection it needs. The 1L bottle is perfect for topping up when required, and the oil meets the correct specifications for many modern vehicles. As a trusted brand, Castrol has a strong reputation, and this product has performed exactly as expected. Overall, a quality engine oil that’s easy to recommend. I’ll continue using it for my Seat Ibiza and would happily buy it again.

Well known brand , top quality . And for once a very good price.

Purchase this every Prime Day as always a great price for a genuine decent product. Oil is ridiculously expensive these days and is worth stocking up

known product at a good price

I’ve been using Castrol EDGE 5W-30 LL for a while now, and it’s hands-down one of the best engine oils I’ve put in my car. You really do notice the difference when you go with a premium oil like this—engine runs smoother, starts more confidently in cold weather, and fuel efficiency even seems a bit better. 🔧 Why I Chose It: It meets VW, Audi, BMW, and Mercedes-Benz LongLife specifications, which was important for my vehicle. It's LL (Long Life) rated, so it gives me peace of mind that the engine is protected over long service intervals. 🚗 Performance: Engine is noticeably quieter and smoother after the oil change. Great for both city driving and long motorway journeys—no performance drops. Helps reduce build-up and sludge, keeping things clean under the hood. 🛢️ Packaging & Use: Comes in a sturdy 4L container with a secure cap and easy-pour spout—no mess at all. The amount is perfect for most cars needing a full change with a bit leftover for top-ups. Trusted Castrol quality with genuine product seal—very reassuring. ✅ Overall: 🛡️ Excellent protection & performance ⛽ Might improve fuel economy slightly 🧊 Works great in cold and hot conditions 💰 Good value for a top-tier product Wouldn’t use anything else in my car now—Castrol EDGE is worth every penny. Highly recommend to anyone serious about maintaining their engine's health and longevity.

Great oil up there with the best very good price

Good quality oil from a brand you can trust! I have been advised by a reputable mechanic that any TURBO petrol or diesel engine will use a little oil, so I carry this in my car as a backup, just in case I need to top it up in between servicing intervals. I trust this oil to protect my engine! Good quantity to carry around and at a reasonable price.
