Lucas Oil 10082 Full Synthetic SAE 5W-20 Motor Oil - 1 Quart (Pack of 6)

I use this in my Ram 3500 with a 6.4 hemi. 154k miles, no lifter issues, MDS still works fine, and not a drop of oil is leaking out of the truck. I change the oil every 10k miles with no issue and the truck weighs 11,400 lbs since day one. It has not had an easy life. Motor is still going strong. Truck says 0-40 but I was going thru 2 quarts at 5000 miles. If you read the manual you can use the 5-40 as long as you are not like zero degrees F. I live in California and here we think 40 is cold. No oil loss with 5-40, it will go the 10k no issue just use a good filter like Fram “Endurance”

Good quality and good price

Great brand.

This was recommended by the mechanic at my local track for use in my Briggs & Stratton LO206 kart motor. I just finished running this oil for an entire season -- close to 30 hours on the motor with zero oil problems and the motor is still in use. This is an inexpensive alternative to the kart specific brands.

This product seems good, but honestly I have no idea if it is since I'm not a mechanic and can't make a well-informed educated decision based on mechanical knowledge.However, it arrived as described and wasn't leaking upon arrival.

This oil was good for me as someone who owns an older vehicle. It’s of a good quality and performs well. It is very viscous oil so it doesn’t leak. I wish it was packaged or sold differently due to the amount that I need so that I could buy it in bulk, but even though it’s more than I would like to spend, so far, it seems to be worth the money.

06’ Dodge 5.7H 4x4 1500 I only use all Lucas products from fluids to speed wax (if I wash the protective dirt layer off) just rolled 356K miles. Also my Onan Genset has 6000+ hours and starts first try every time.

very good stuff
