Decent for the price

Needed some oil for my older car and found Archoil.com. The website was pretty straightforward to navigate, which I appreciated, didn't have to hunt around for what I needed. Placed my order and it shipped out in a reasonable amount of time. The packaging was okay, nothing fancy but it did the job, no leaks or anything. The oil seems to be doing what it's supposed to, no complaints there. My only minor gripe is that the shipping wasn't super fast, took about a week to get here. Not a huge deal for me since I wasn't in a rush, but something to keep in mind if you need fluids quickly. Overall, it's a solid 4-star experience.

Good stuff, just a minor delivery hiccup

Finally decided to give Archoil.com a try for some engine fluids. I'd heard good things from a few car enthusiast forums, so figured why not. Ordering was straightforward enough, the website is pretty clean and easy to navigate, no complaints there. I picked out what I needed, paid up, and got the confirmation email pretty quick. The actual delivery took maybe a day longer than the estimate, which wasn't a huge deal but worth noting if you're in a real rush. Everything arrived well-packaged though, nothing spilled or damaged, which is always a relief with fluids. The product itself seems high quality, definitely noticed a difference in how smooth things are running. I'm happy with the purchase and will probably order again when I need more. Just tighten up that delivery window a tiny bit.

Easy to order, works well

So I grabbed some of that AR6400-D Diesel Fuel System Cleaner the other week. My diesel felt a little sluggish, you know? Ordering it was super easy online, didn't have any trouble finding what I needed. It got here pretty quick, like 4 days to my place. Threw it in the tank and after a couple of fill-ups, the truck feels a bit livelier. No complaints, it did what it was supposed to do and the whole process was smooth. Definitely happy with it.

Good product, minor shipping issue

I bought the AR9100 Friction Modifier, 32oz size, for my truck. The product itself seems to be working as advertised; I noticed a slight improvement in engine smoothness after a few hundred miles. The price was competitive, especially with the bulk buy discount I got. However, shipping took a bit longer than I expected, around 7 days to reach me in California, which felt a little slow for an online order. The packaging was good though, no leaks or damage. Overall, I'm satisfied with the purchase and the product's performance, but faster shipping would make the experience even better next time.

AR6900-P is a game changer!

I just had to leave a review for the AR6900-P Max Advanced Petrol Fuel Conditioner! I put it in my car and the difference is totally noticeable. My engine feels so much smoother, and I swear I'm getting better gas mileage already. The website was super easy to navigate, and my order got here quickly, took like 3 days to reach my door! I'm absolutely buying this again, and I'm telling all my friends who drive gasoline cars about it. What a fantastic product!

Decent enough, but had a small hiccup

Finally decided to give Archoil.com a try for some engine oil I needed. The website itself was pretty straightforward to navigate, which was a plus. Found what I was looking for without much fuss, and the checkout process was smooth enough, no real complaints there. The oil arrived in about a week, which isn't super fast but also not terribly slow, just average I guess. Packaging was okay, nothing fancy but it kept the product safe. My only minor gripe was that the tracking info didn't update for like two days in the middle of the journey, so I was a bit in the dark there. The oil seems fine, doing its job, but that tracking thing was a bit annoying. Overall, it was an okay experience.

WOW! My engine feels brand new!

Okay, so I finally decided to give Archoil a try for my car, and OH MY GOODNESS! I'm absolutely thrilled! I've been feeling like my engine was a bit sluggish lately, you know? Just not quite as responsive as it used to be. But after using their oil additive, it's like a completely different car! The difference is genuinely noticeable. My engine feels smoother, quieter, and it just purrs now. Seriously, I wasn't expecting such a huge change, but it's incredible. I'm definitely going to be a repeat customer. Like, for sure! And I've already told all my friends with cars, they HAVE to check out Archoil.com. This stuff is a game-changer!

Archoil products are top notch

I've been using Archoil products for a while now, mostly the AR9100 for my diesel truck, and I gotta say, it makes a noticeable difference. This last order from Archoil.com was for a friend who wanted to try it out. Ordering was super easy on their website, very straightforward to find what I needed. Delivery was pretty quick too, got it in about four days which is decent for fluids. Packaging was solid, everything arrived intact, no leaks or anything. My friend is already seeing improvements in his engine's smoothness, so that's a win. Definitely happy with the quality and the whole purchase experience.

Anyone know if they allow multiple discount codes? Got one from an influencer and then saw a Black Friday one, tryna stack them boys.

S Steve P. 3 months ago
Nah, pretty sure it's one per order. Tried it before with a couple codes and it only let me use one.

Hey, thinking about grabbing some AR9100 for my truck. How long does shipping usually take to like, Ohio?

I'm in Michigan and it usually takes about 4-5 business days for me. Not super fast but not bad.

Mine got to PA in like 3 days last time. Depends on what you order maybe? And if you hit that free shipping threshold, that helps too.
