Engine oil LIQUI MOLY or AMSOIL

I changed to that and really happy with it so far, shifting is butter smooth.

Been using Liqui Moly since last 4 changes when a mechanic got emotional explaining how Mobil 1 is good, but if you are going such a long trip, oh man got for Liqui Moly, the best of the best, his reaction was almost orgasmic.

And I have loved the performance, lower noise, possibly good fuel economy, a 30 mpg+ on a 7k km trip last year.

For anyone who doesn't mind spending an extra buck, try Liqui Moly.

Based on my own tests, I found the AmsOil to be the best at reducing heat a few degrees. It's not cheap, but it's still cheap insurance, all things considered.

I use Amsoil 20w50 in all 3. You don’t need a different oil for the trans. Amsoil is not cheap but I’ve been using it on my 03 FatBoy since new and have had no problems.

I used this because it was on sale:

Liqui Moly - 0w-30 Oil (5 Liter) Top Tec 4210 (504.00/507.00 spec)

I figure if it meets spec, cheaper is better for a midcycle top change.

Originally switched to Amsoil for the Noack rating but stayed because it's just good stuff. I now run Amsoil products for all fluids in all vehicles.

I use AMSOIL 5W-30 for both of our vehicles. Never had any issues on either vehicle using AMSOIL.

I use Rowe oil or LiquiMoly in my TDI, been happy with either.

Amsoil Signature 5w-20 + K&N Gold oil filter (HP1017 for 4th gens, not sure about 5th) is arguably the single best combo if you can afford the oil. Your lobes will thank you.

I just switched over to amsoil and my mpg went down marginally. Also using the PPE larger oil filter 10 micron filter.
