Engine oil AMSOIL or ZIC

Been running amsoil in my Vitpilen 701. Same engine and it's been great. I run the 15w-50 metric stuff though.

I’ve run amsoil in all my bikes and still do. Same with all my cars and trucks. Never had issues

For me amsoil signature series 0w20 a lot better than ravenol ehs 0w20.

I'm regularly using amsoil ss on my Honda L15z1 engine almost 7 years.

0W-20 Amsoil Signature Series 100% synthetic oil changed every 5k miles. Wix 57173XP filter.

I’ve been using it as well for nearly 50,000 kms now in my personal car without any issues.

ZIC - Dito ako nag stay, ang tahimik sa makina, both matic and manual. Malamig din sa makina.

Personal experience ko from 15W40 Delo Gold to Zic 10W40 to 5W30 Full Synthetic sa 1.6L Diesel Accent mas naging responsive & rev happy yung makina sa 5W30 Full Synthetic kahit sa 10W40 kasi na Full Synthetic hindi siya happy parang pigil yung makina & less responsive siya.

As an avid user of AMSOIL, it’s a noticeable difference, amsoil is the king

I did have a 1982 diesel Jetta go 435,000 miles on oem int. shaft bearings. I had access to a lot of free Amsoil back then....so, that may have helped. However, I think it over-lubed the cylinder walls though. Rings weren't exactly what you would call 'tight.'

I am not hating on Amsoil. I am running their engine oil and ****ing hate it. burned off another quarter of a quart in the last day of driving... ive never had this kind of consumption before and there are no leaks...
