Cheap Red Line 5W30 Synthetic Oil - 1 Quart, Pack of 12

Customer Ratings:

I have owned two Subaru WRX's over the past five years and have used many different types of synthetic oils in them.

I notice that Redline's oil seems to degrade and burn-off less than other oils...mainly Mobil1. I would recommend this oil to people who drive turbo cars aggressively. Not all synthetics are made to the same quality and it seems like Redline is one of the better brands. I also recommend their gear oil for transmissions and differentials.

Decided on Redline after much research on the best "ester based" synthetic oil. This is my 5th oil change to date with Redline 5W30 going about 5200 miles between. In the past using dino oil and other synthetics I would notice a huge difference in smoothness both at running speed and idle immediately after a fresh oil change only to wane midway through oil change cycle. Not with this oil, engine is just as smooth even at the back end of 5200 miles. Probably could go a couple of thousand more on this oil. It would be interesting to send in a used sample for testing just to see how much accumulated particles from wear are there. I trust this oil to wait a bit longer for my next oil change if need be, the protection is there.

After reading all the information regarding oil, zddp additives, (lack of) API certification, I bought 24 quarts for my brand new Honda Euro (Acura TSX). I won't be fooled by the API sticker, as it does not signify or indicate the quality of the oil.

I wasn't expecting to tell much difference after just 1000km on the odometer, but the difference was there! Time will tell how well those additives work, but I have faith in Redline.

Notable difference in how smooth the engine runs. Oil should last for 7500mi as well (according to website), so you can get that extra protection for your engine and save some money too. Great buy!

Had the ticking noise common in the later VQ35 engines. The very expensive blend Nissan was known to solve this but I gave this a try and it worked for slightly less money and benefit of full synthetic formula.
