Best oil I've used
AdamSubaru123 5 months ago
Used to use Rotella T6, Noticed I was getting a bit of piston slap anything below 30ish degrees, tried out this stuff for a change and even at 15 degrees the piston slap is gone! Motor runs nice and smooth. Definitely worth it.

After my oil change I noticed almost instantly how much smoother my engine feels overall. Compared to when I used the recommended model 1 from the dealership. Redline has my 14 sti feeling and sounding much more healthier

This oil was oily... so I guess it does a good job. My '06 WRX is still really fast so I'm guessing this is a great product!

Second oil change using this oil, it was barely even brown When I pulled it out after 5,000 miles. Kind of pricy but definitely worth it.

This oil is absolutely amazing. It took me a while to think this, with normal driving I noticed I burned little to no oil while on Mobile I burned a bit, it stayed a lighter color much longer. But what really hit home for me with this oil was taking it on the track. At 3500 miles I took my car (with over 200k on it)to Subiefest and ran it on the track at Auto Club. After each twenty minute session in 102 degrees I checked the oil, after the first couple sessions I was quite impressed that I didn't lose even a tiny bit. But what really got me when I didn't lose any throughout the entire day. I ran my car all out in each session, so seeing that the oil level remained the same, and color remained the same, really made up my mind on the awesomeness of this oil. I plan on using Redline from now in, in all my applications.

  • Q: 5W-30 or 10W-40?  taylor822 3 years ago


    I drive a semi built 2003 WRX and I live in Seattle, WA area where the weather is pretty mild all year minus a few summer months, would it be safe to run 10w40 or will it be too cold?

  • Q: UOA?  Tmanjustice49570 5 years ago


    Anyone ever seen one for this oil? Just curious on how it looks afterwards.

    • A: It really depends how long the oil is used and what kind of wear and tear it has gone through while in the vehicle. I have had excellent results in the past, the oil was still relatively clean after 6000 miles both on track and off. A little burnt or darker than new but still clear and holding it's original lubrication properties to the best of my knowledge.

  • Q: Which oil?  Mattio239 5 years ago


    I have a 2008 sti with stage 2. I also live in Florida in regards to the warmer temperatures. What type of red line oil should I use? Seems like most use the 5W30. Thanks

    • A: Subaru recommends 5W30, however most people will run a bit thicker oil in hot climates and thinner in cold climates. So for you in the summer a 10W30 might be better, and 5W30 in the cooler months of the year.
