11305 10W30 Motor Oil, 1 Gallon, 1 Pack

First and foremost, I want to highlight the exceptional experience I’ve consistently had with the seller, R/A Hoerr Incorporated. Over the years, I’ve purchased numerous automotive products online, and this company stands out as one of the best I’ve ever dealt with—especially when it comes to Red Line products. Their shipments are always prompt, packaging is professional and secure, and everything arrives in excellent condition, without exception. Their attention to customer service and reliability has made them a go-to source for my automotive needs. Now, turning to the product itself—Red Line Oil—I’ve been using it for well over 30 years and can say without hesitation that it is among the highest quality motor oils available. I’ve trusted it in a wide range of applications, from daily drivers to high-performance drag cars, and it has never failed to deliver outstanding results. The consistency and performance of Red Line products have earned my complete confidence over decades of use. My trust in Red Line was firmly established nearly three decades ago during an engine rebuild on a vehicle that had logged over 260,000 miles. What I discovered during that teardown left a lasting impression: the cylinder walls still showed clear and well-defined hone marks, the cam lobes were in near-pristine condition, and both the bottom-end bearings and journals displayed minimal wear. It was a powerful testament to the product’s protective capabilities under long-term stress. Since that experience, Red Line has been the only engine oil I use in any of my vehicles. I also make it a point to follow proper maintenance intervals and always pair the oil with a high-quality filter. When these best practices are combined with a premium lubricant like Red Line, the longevity and reliability of your engine are virtually guaranteed. In short, whether you’re looking for peace of mind in your daily commute or maximum protection for your high-performance build, Red Line Oil remains a top-tier choice—and R/A Hoerr Incorporated is the best place to get it.

I have a 91 miata and have switch around from different brands because didn't like the idea of having to order oil online, but man..... talk about night and day difference.. on cold starts I use to get a tick for the first second while the engine builds oil pressure, but not anymore... starts up nice and smooth everytime. I've put about 2k miles on the oil so far, and not that I had sluge in my engine before but I looked in my oil cap the other day and the little bit of build up that made its way there over the last 30 years is not all gone and clean. Really amazed by the quality and the fact it's a american made oil. Go on YouTube and look up project farm he has a Playlist where he compares oils, and redline didn't win, but man did it come close, it should have won in my opinion. Also owning a miata which revs pretty high and cruzes at 4k on the highway it seems to handle the abuse without foaming. And on the forms all the miata guys rave about how great this oil is, and I'm a believer now. Only oil that will ever go in my miata for the rest of its life.

WAY too expensive, but oil works well. I would use in air cooled engines, because the oil does a great job at lubrication. Like a vintage motorcycle, or something like that. Something you are willing to protect at any price...

My husbands prefers to use this oil for his subi, he had thr motor rebuilt and this is the best oil.

Too much zinc ... Your engine will work quiet, but it will slowly kill your catalytic. When zinc burns, it turns into glass and clogs your catalytic converter.
