Engine oil Castrol or AMSOIL

amsoil is so much better

I like using Amsoil because its very good at withstanding heat.

I use Castrol EDGE 5W-30 LL Fully Synthetic Engine Oil on my B48 pre LCI G21 no issues at all and complies with BMW specifications

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 have a 2010 Jetta TDI cup edition with the CJAA engine and the factory spec listed in the manual is 5W-40… On top of that the oil cap alone has Castrol on it\nSo Castrol 5W-40…. End of story…. I apologize if I sound condescending as I do not mean to and also recognize you may have purchased your vehicle second hand and it may have not come with a manual… But if the top of your 710 aka oil cap says Castrol on it and you truly have a CJAA engine then I guarantee you that Castrol 5W-40 is the proper oil regardless of location or climate Ps…. Anyone who claims to use or recommend anything else has also probably had massive engine problems or engine repairs an question why they had those issues Follow factory spec and maintenance recommendations…. I’m pushing 280k on my CJAA engine without a single issue

Amsoil Signature 5W20

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

Using Amsoil. Nung pinalitan ko valve gasket ng 2008 Vios ko walang sludge. Gold ang loob.

I have used Castrol and it seems fine.

Forget Castrol LL! Its a VAG Killer Oil. In this Case Mobil 1
