Owner reviews for engine oil

10w-40 Mobil 1 is the best oil you can have for your VR6 engine. Besides superior protection it also takes longer for the oil viscosity to break down.

Castrol A747. The only failure I've ever had was down to incorrect assemble. Smells lovely too!

I always ran the Motul Grand Prix in my shifter, I never had any engine problems. Still run it in my dirt bike, I love the smell of it, too.

I've used Mobile 1 in my 2.4l GM LD9 since new and it now has 188,500 miles on it with zero engine problems. I changed the timing chain myself at 160,000 miles (recommended at 150k) and it looked new with plenty of life left in the tensioner and guides. I also pulled the head and everything was shiney metal, no pits, grooves, or hot spots (uneven wear spots).

But on my motorcycle, I use Mobil 1. Yes, auto oil in a moto engine.

I use Mobil 1 on my cars. I also do a lot of off road driving which puts a good deal of stress on the engine. It's pricier, but I'm fine with paying for the added protection from additives and ability to not breakdown as much due to heat since I'm putting the engine under heavy loads at low speeds much more often than the typical consumer.

I have only used Lubromoly/Liquimoly 5w-30 Full synthetic with the Mos2 Additive. Molydenum sulfide from liquimoly and my car runs super quiet and idle very smooth. I change my oil every 2500 miles..no matter what. Oil pressure is very good, zero shavings in the oil between oil changes. Additionally, I use the liquimoly engine clean between changes and like I mentioned before the car runs superb...no complaints here.

5 quarters of mobil 1 0-40 and 1 quart 15-40 mobil all syntetic, runs like a champ and very quiet

I use Castrol Syntec 10w-40 in all of my VR6's and change it around 3000-4000 miles with oil filter (Meyle, Hengst or Topran) I use it in my MK4 and even in my old ass MK3 and never had any problems whatsoever. My MK3 VR6 that a sold a few months back, a.k.a. The Silver Bullet, has over 150K miles on the odometer and still counting and she runs like a beast. The lifters are ticking a bit loud but that's common for any high mileage VR6 engine.

I use MOTUL for my oil.
