Red Line (15305) 5W30 Motor Oil - Full-synthetic Ester Formula Car Engine Oil - 1 Gallon

BMW 335is loves it.

Used in the engine of my 1992 Nissan 300ZX Twin Turbo.I will never use any less than Redline oils and I highly recommend them.

This is without a doubt the best motor oil on the market. Over the years I've used various different brands of synthetic including Mobil 1, Castrol Syntec, Pennzoil Platinum, & Liqui Moly just to name a few, and Redline is the only brand I've tried that made the VQ37VHR motor in my Infiniti Q50 run smoother and quieter. I went from Mobil 1 Extended Performance to Redline and I immediately noticed smoother and quieter acceleration, and during idle the engine is barely audible. I have also noticed a slight improvement in fuel economy as well. It's hard to believe that going from one motor oil to another in the same viscosity could make any noticeable difference in engine operation but in my case it definitely did because the engine really does feel happier and healthier with the Redline oil.There's also a lot of good information out there that shows Redline oil can actually reduce oil temperatures as well as keep your engine cleaner. And the added detergents, ZDDP, molybdenum and ester molecules can really help to reduce friction & engine wear and keep the engine clean over time. But the synthetic ester base is what really makes the difference between Redline and all of the other motor oils out there, and it's what also accounts for the increase in price.The only downside is it's expensive when compared to most of the other synthetic brands out there, but this is an Ester-based Group V synthetic motor oil that is aviation grade, and you get what you pay for. For me it's worth spending the extra $15 per oil change and I'm definitely not planning on switching to any other motor oil again as long as the Redline continues to perform this good.

Mini cooper s used a daily driver 40 to 60miles daily burning through a quart every few weeks, bought this with hopes high burn off temperature and I think it does the trick! 1500+ miles & oil levels still good.

Quieted down my 11 Ram 5.7L valve train / HEMI Tick used to use PUP 5w20 and do religious oil changes every 5000Km with mopar filter and the truck had the warm Idle HEMI tick from the lifters and valve train, still might need cam and lifters eventually butRead lots of good reviews about redline oil helping with the Tick was sceptical but I tried the redline 5w30 and I will never go back truck runs so much smoother and quieter now, redline has made me a believer. Side note I am also running the Wix 51085XP filter. Also for those wondering the 5w30 is fine in our trucks some say it will mess with the MDS but I have not encountered any problems, The Powerwagon 6.4s take 0w40 and MDS is fine, I also have an 03 2500 5.7 and it calls for 5w30 but I’ve been running rotella 10w30 all year round for years and the truck just rolled over 450000Km and is still running like a champ. If you got the HEMI tick (Not broken exhaust manifold bolts) give Redline a try you might be surprised.
