okay naman ang Zic, which variant will you be using? Sa office namin halos lahat ng sasakyan, trucks and forklifts included, Zic X6000 ang gamit namin in the last 5 years, never had an issue with it
I have a 2012 gmc terrain 2.4l currently at 202k. I’ve used Lucas oil and restore and protect Valvoline oil the last 50k. Still runs like a gem with 177-182-179-175 compression cylinders 1-4. Used to be 155-149-144-168 before I started using both these oils
I exclusively have used Lucas oil for my sportster motor for 5 years. The bottle looks cool, that's it. Full synthetic oil, no frills, cheap, and easy to get.
I tried 10W40 in my car as 5W40 was beyond my budget at the time and it's been great.
Before 2023 i was using zic 0w20 but caltex has newer technology
Used this for my old Alterra that made it to 250k mileage. Good budget option.
I like the Lucas ones personally.
Lucas OS works great. It's some amazing stuff, BUT. Do not go over your oil change intervals. Once the Lucas additive starts breaking down it turns to a nasty varnish. Went 7k using synthetic amsoil z-rod and Lucas OS, on a new rebuilt 4.0l. Lost a lifter and ate up the cam lobe.
That looks like you dropped a valve. Yes Lucy’s oil will help. It will lubricate the chamber so you can take out all the pieces.
I’m currently living in Korea and switched to a ZIC SK Enmove X8 5w-30 full synthetic and OEM Kia filter 26300-35505. Pretty much directly after ticking started.
