Red Line 5W30 Motor Oil - Quart - 15304

Great Gear Oil!

First time I have used Red Line gear oil. Glad I did! It has smoothed out the shifting on my 1997 Jeep Wrangler.

I won't use anything else

I use Red line on all the Harley motors I build and have never had any issues with startup and break in. That includes the early knuckleheads up to the twin cams. Thanks for your superior product.

Great product

Ordered the gallon jug and used a hand pump which fit perfect on the top of the jug. Great reviews for MT90 so went with it.

Good for both high performance and every day use

I have used Redline oils in all my vehicles for 5+ years now, never had any issues, it is excellent for both high performance and every day use.

Great product

Just a great product that's all I got to say. No chadder from the rear diff.

2014 RAM 4X4 65RFE XSMN / REDLINE C+ ATF

I dropped my xsmn pan drained all the factory fill ATF out changed the sump filter & seal and changed the spin on filter . I also installed a Mag-Hytec 45-RFE extra fliud capacity pan with a drain plug ( Great pan !) I poured in about 8 1/2 to 9 Qts of the REDLINE C +ATF and I swear it shifts smoother and runs a bit cooler than it ever has ! I did this at 47,000 miles on the truck , I also changed the Xsfer case fluid with the REDLINE C + ATF as well . It's been over 1k & still shifts great !

Red Line's D4 is best atf

When I switched from operating manual's suggested dexron iii atf to red line d4, my car's passing acceleration was much better than before. Although my mechanic recommends to change the atf every 10,000 to 15,000 miles for conventional oil, I checked with Red Line. They recommend to change my atf every 30,000 to 40,000 since their oil is all synthethic. This is worth every penny.
