  1. When Only THE BEST Is Good Enough, Use Red Line Oil
    Here’s a crazy thing, in this day and age: Pick up the phone and call the company that makes the oils for your car.. they ACTUALLY pick up the phone.. Tell them you have questions about which lubricant is best for your application… and they transfer you to the engineer who actually works on production formulations!Yes, this can be you! It was for me. I have called them several times over the years, they are based in California and they are actually friendly and willing to discuss your application!I cannot recommend them enough. Yes, this is a premium oil, it’s not the cheapest.. but the quality is recognized world wide, from formula one to Baja to marine racing, to industrial lubricants and greases.. these guys are the best.No, I don’t work for them.. I am just a Customer.. and I remain their Customer because of product quality and Customer support. The best, hands down.

  2. Best oil on the market! Just look at the spec sheets!
    Red Line Oil is worth the extra money to know that you have quality and dependability. I use it in all of my vehicles, including my diesel pusher motor home. Read the specifications, not all oil is created equally. The extra money on maintenance will save you in the long run!

  3. Expensive but worth it.
    The best synthetic oil imo. Been using it in my 2006 5.9 Cummins since new. Never had a single hiccup. Truck now has 170k, expecting it to go another 200k.

  4. Best Quality Motor Oil Available
    They stuff is not cheap but provides superior protection for your valuable vehicles.

  5. 100,000 mile +
    Purchased a 97 chevy with a 350 and 70,000 mi. Put Redline in it. Changed filter every 10,000, tested compression with 170,000 and was better than factory specs. Currently have duramax with 480,000 mi. Change oil every 20,000. Original transmission has 180,000 towing mi. on same oil.My Uncle ran 100,000 on all his vehicles and was Sponsored by Redline. He regularly tested his oils. He did a transmission service done by local shop on his motor home. 120,000 miles and the test said oil was still good just like every other test.IT’S WORTH IT & BETTER FOR ENVIRONMENT.

  6. Great oil, I can now change it once a …
    Great oil, I can now change it once a year on the 6.4 Powerstroke (all my samples from Blackstone came back great) versus every six months with a conventional oil. This ends up saving me time as the cost is a wash between eight gallons of quality conventional and two filters… and we all know time equals money.If you want the best, you pay for it. This is worth it. I run it in the axles, the transfer case, automatic transmission, other vehicles, etc.

  7. This was recommended to me by a mercedes mechanic who recommended this …
    I run this in my 2012 Mercedes Benz ML350 Bluetec diesel. I live in Vegas and engines get fire hot in the summer. This is the only oil that will stand up to high diesel temps and new emission requirements. This was recommended to me by a mercedes mechanic who recommended this over any other oil since it uses the ester based core not the conventional based oils. Do some research on vapor temps on oil and you’ll want the same.
