Engine oil PENNZOIL or AMSOIL

Also, I have upgraded to Amsoil Synthetic Engine Oil which further helps for maintaining DPF health as it reduces ash that can accumulate and plug the filter.

99 Ls400 owner. Pennzoil Ultra Platinum every 5k miles.

My brand new one acted the same. I did an oil change at 1000 miles and went with Amsoil Hybrid 0w16. Since the oil change I really don\u2019t feel the vibration, much smoother.

Pennzoil Platinum Euro full synthetic 5W40 on my Abarth. Same weight as written on the engine oil cap and in the user's manual. 5l jugs easily available for $40 CAD plus HST.

Pennzoil Euro Platinum 5w40. This oil is slept on but out performs most other expensive oils outside of Amsoil.

On my 25’ Ranger Raptor I’ve done oil change at 500, 2500 and 5000 miles. Will continue every 5k. I run Amsoil signature series 5w30, with MC filter. Ford recommends 10k.

I had an 05 Corolla, it was my Amsoil testbed. After the first two oil changes for break in at 800 and 10k, only one oil change per year, 20-30k miles. Amsoil oil and filters.

Nice work. My 2012 camryil4 se gets new oil every 3k 0-20 pennzoil ultra syn. 112,000 mi.

AmsOil 10w30 for turbo engines... haven't had any issues yet. Still consumes it though.

Amsoil's biggest 'benefit' is a longer service life. Their additive pack doesn't break down as quickly, so you can run it longer between oil changes. However, if you're paying twice as much and running it twice as long, it's a wash and you're not gaining anything. When I was selling Amsoil, I had a modified 4 banger and a high mileage 24v that had both been running Rotella for the entire time that I owned them before switching to T6 when it was introduced. I pulled UOA samples every 1k miles, then switched to Amsoil Signature after 5k and did the same thing except I pushed the Cummins to 10k. Zero improvement in fuel dilution, wear markers, or carbon build-up. After seeing there was no real-world benefit, I stopped selling it. I won't market a product I don't believe in, let alone one that I see as an outright scam.
