Engine oil Mobil or Shell

It completely transforms the bike , it resists heating like it almost non existent even after a hard session of riding, performance is consistent in warm up, cold start or all kinds of situation ,fuel efficiency definitely increased, and the acceleration is also noticable better and power is also good compared to when I used to run on liquid gun and on highways the bike totally becomes a beast . I highly recommend shell to my fellow riders, it's the one that completely suits RE engines

5 qt jug of M1 and a wix filter runs me just under $30 for most vehicles, and the oil is better than the conventional bulk crap most oil changes places use.

if you buy oil from Walmart, 5qt of mobil 1 or similar is well under $30. i buy the Mazda OEM filter/washer combos in a pack of 5 for like $6 per filter. so my oil change is around $34 (plus $10 for a bottle of techron) and i know i didn’t fuck it up.

for my 2025 camry, I get a 5 qt bottle of mobile 1 0w8 for $28 at walmart and a oem filter for about 5 bucks from the dealer with the washer, so a change for $33 bucks total.

I've been using Mobil 1 European blend 0w - 40 full synthetic. It's done me good for well over a year now.

I get my oil from Sams for about $60 for 4 gallons. I use the Mobile Delvac and haven’t had any issues.

I switched to 5w30 shell from 10w30 havoline.

No problems. The engine is a little bit cleaner.

I am using Shell Helix Ultra 5w40, fully synthetic for my Lancer (2006), change it at around 7000 KMs. No complaints, my travel includes short & long distance, very happy & satisfied.

I work in the automotive industry; and by far, Liqui Molly, Motul, and Total exceed Mobil 1. Mobil 1 has the recognition and they worked hard at marketing for many years. Independent German studies conclude that they are 3rd place at best when it comes to \"good quality\" oils.

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.
