Engine oil Shell or PENNZOIL

Been using Shell’s HX7 for 7 years now, so far okay naman.

Shell Long Ride, OP. Tested ko na 'yan and super okay niya. Been using it for a long time narin kaya im sure na goods 'yan!

For Pennzoil, I always use the Ultra platinum over the standard platinum. It has been tested to have lower friction and higher addictive content.

I have had a much better experience with Pennzoil in Japanese cars. Pennzoil is a bit better.

Rotella t6 5w40 all day every day. Run it in my focus st. I noticed less oil consumption, cleaner plugs and less soot just after the second change

Don’t use royal purple heard so many bad things about how it’s not a good brand anymore, I swapped to penzoil oil plantinum 5/30 and honestly the car feels a lot smoother and sounds a lil less ticki but still I’d recommend anything other than royal purple

One poster said it right; Amsoil is a Multi Level Marketing program and that's why it's so expensive. Yes it's great oil, however, the Penzoil ULTRA Platinum is high in detergents that keep your engine clean. It's made of natural gas, an industry first, and is so pure and clear you can hardly see it on your dipstick.

But if high quality oil tulad ng Shell na fully synthetic, i go as high as 3k.

Rotella T6 Full Synthetic 5w-40... Burns a little.

When I tried it on my MT-07, though, I found a lot of false-neutrals that my bike didn't have before. I drained it out and put Motul back in after about 300 miles.
