G,day Scotty you Weapon you.

First I would like to say that I am a fan and love your content even though I am from Sydney Australia.

My name is Leon Gyarmati,  I am 30 years old and have been a mechanic now for 12 years, so far having completed an Australian certificate 3 in light vehicle automotive technician, i have received Subaru academy training, I am a recognized qualified professional mechanic for all makes and models. (not that i am familiar with all, i am only young and have much to learn i just wanted to tell you that i am a qualified mechanic just like yourself)

Due to dealership politics that i have no care for what so ever i no longer work for Subaru, instead have attempted to become a sole trader and start out on my own so far

slow and steady she goes.

I really enjoy watching your videos on you tube they make me laugh and feel good, so please don't stop.

Anyway my question to you is:

Subaru upper cylinder cleaner, I suspect its much like sea foam (We don't get sea foam here) except Subaru have their own version called upper cylinder cleaner.

Subaru supply 1 can as a part of every service that is to be put into the intake manifold.

If you have ever heard of it, I would love to see a Video on what you think and if it actually is necessary for Subaru engines, especially the older EJ Boxer series engines due to the excessive carbon build up compared to the newer FA and FB boxer engines, inline and V engine configurations.

Thank you Scotty.

I hope to hear from you soon.

Best regards and stay safe and well to you and your family.
