Engine oil VALVOLINE or Shell

Just switched from unioil 10w-40 motorcycle oil (for break-in period) to Valvoline premium protect 10w-30 on my pcx160

Di ko alam ganun pala ka laki difference ng oil!

Grabe nawala yung akala kong normal vibration

Mannol 5W30 the one with JP at the end

Shell Helix Ultra 5W40 if you like to experiment, will make your bug quieter, but you will discover other noises (like tires, rattles of the trunk cover, gear noise, compressor of aircon).

Best you can do is get your hands on some Restore and protect, 5w30 is fine, 0w20 will get you better fuel economy but a little more wear and obviously 5w40 is the other way round.

Been using Valvoline Restore and Protect so I’m gonna change it even more frequently for the next few changes

My truck is rough cosmetically, but the engine runs beautifully at 175k.

Im currently using it in my car (2017 Ford Fusion 2.0 Ecoboost), and just made a long road trip around 2k miles in the summer heat, some around 100 degrees. The oil looks fine, not really dirty in my case.

My prius went from burning a quart every 1000 miles to almost no consumption after 2 changes with r and p. The oil was so disgustingly dirty the first change which i did at 3k instead of 5k. It definitely cleans your engine out.

Shell Rotella T6 5w40 and Tokyo Roki OEM filter all day everyday.

Both oils significantly reduced oil consumption

I just found this thread. I have a 2014 Jetta 1.8t with 107k that I bought for my daughter two years ago and it burns through a quart of oil about every month. It dropped cyinder 1 similar to what the other person experienced, but new plugs and ignition coils solved the problem.

I did use the Shell T6 Rotella 5W40 for 4 OCI's and then got a misfire issue. When my mechanic was going thru the possible symptoms he asked what oil i used. When i told him it's a full synthetic deisel truck oil he shook his head and said that not a good idea. Too thick, and that could have an impact.
