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
I run rotella t6 5w-40, and she loves it
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.
We use rotella t-6 5-40. Have put on well over a million miles between our vans and its been good. 10k intervals. We have on a 2019 with 260k. Never had any issues. Still on our original DPF. So it's safe to it's low ash oil.
Shell. Literally makes my vehicles dead silent after every oil change.
10W40 on my 1995 Camry
20W50 on my 2015 Toyota Hiace
I use Shell Helix Ultra 5w40 on my m52b20 E39 and I'm super satisfied
For example my previous BMW engine was very noisy with mobile 1, and quiet with castrol
HP Prolube is a very low quality oil compared to other oil brands in the market. Castrol has good head sound dampening, as does Rowe, both great for gear shifts and clutch feel.
