Engine oil Shell or AMSOIL

The dreaded Pentastar tick is GONE! It took about a week of regular use for the noise (on the passenger side of the top of the engine) that used to show up after idling for a few minutes to completely disappear with the new oil. I’m sure plenty of oils work fine but I went with Amsoil because my brother gave me a gift card and referral coupon for my birthday. I run 6 qts because I already have the Baxter spin-on adapter. Which requires a little more oil. The dipstick reads “low” at 5 qts whether I’m idling or checking it after the Jeep has been off for ten minutes. With 6 qts it sits right and holds a steady 30 PSI and never spikes. Such a relief!

I wouldn’t go with 0W20. Most people thicken the oil up in these when they start getting excessive oil burning. Lots of folks running Rotella 5W40. I ran it for years before I got tired of paying the premium price.

I run rotella t6 5w-40, and she loves it

Amsoil Signature 5W20

I use AMSOIL engine oil and coolant in mine for the 5 years and have no issues in that department.

10w30 Rotella will cut your oil consumption by 70-80%, ran it in my last Subaru until the clutch went at 234k and running it in my current Subaru

Change the oil with Rotella T6 oil.

I use Shell Helix Ultra 5w30 in my 330i car. It also has BMW Long Life certification. I'm very satisfied with it and would recommend it to you. It also offers good value for money compared to other higher-end brands. You don't get better performance for the money you pay.

I never ran Pennzoil, but I have Amsoil. Amsoil is good, but too expensive.

I run the diesel Rotella T6 5w-40. My catalytic converter decided to start throwing P0420 codes around 58k miles and I spoke to a shop that I am going to have tune my car and one of the techs said that they reformulated T6 a few years ago and it has more zinc in it than it used to and that might have had an effect on my cat and it's early demise.
