Engine oil Shell or AMSOIL

Have noticed on several times that when I went from Subaru OEM oil to Amsoil BACK to OEM that it runs much quieter and smoother on Amsoil.

But I run Amsoil signature blend in my vehicles. And I also push 15,000-25,000 miles per change.

I have seen my friends and family use amsoil for 25000kms each change and their cars do 200k- 300k without any engine issues.

I already added to engine oil and transmission. 5mpg improvement avg. already.

Switch to Amsoil products and go every 6,000. I honestly would go every 7500 with it if it was me driving that much.

I use Rotella T4 on my 2.5L and have been for years because high ZDDP helps with the valve tapping I have going on. It has actually gotten quieter over time and feel the engine is running smoother than ever.

Send your used oil to Blackstone or Amsoil for analysis and all of your questions about oil will be answered.

I’m using the 0w16 from Renault that probably is a Shell RN17, I have about 25.000km now and I will do the third change on the beginning of next year… but in the sandero that I also own I changed to 5w30 (from 0w20) both RN17 and the engine feels way softer and silent…

Rotella T6 5w40 in my EJ255, its helped a tad with the leaking until I can get everything apart to seal it all up again.

Absolutely Liqumoly!

Please never put Amsoil in a Volkswagen they under rate their viscosity/ wt ratings and the only time I used their oil I ended up spinning a rod bearing in my first R32
