Engine oil OEM Toyota or Lucas

Use toyota 0/16. Or Mobil 1 0/16. Liqui moly is also very good.

Fun fact, on a gen 4 Toyota Camry (1997-2001) with the 5S-FE 2.2-liter four cylinder, the low oil light doesn’t even come on until you’re like 2.5 quarts low!

I paid $67 for 4 qts of lucas full synthetic oil and a filter on Amazon and just grabbed an O ring from harley. Harley's oil is fucking garbage. Lucas, Amsoil, Motul & Mobil 1 full synthetic are all damn fine products.

I used lucas in my honda and will use it on my next change for harley

Personally I run Lucas oil in mine, not just my current zzr600, but even my older vintage bikes when I had them. It isn’t crazy expensive and is high quality.

My 2014 had 226K changed it at toyota every 10K no issues

I run Lucas in all 3 holes and my bike has been cooler, less noise and shifts smoother than it did when I got it and it had Harley fluids in it.

I paid $15.85 per US quart for Toyota Genuine 0W8 oil in Canada.

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 used Toyota OEM oil twice and was disappointed by the way it changed color at less than 5,000 kms. Two different mechanics asked me if I had delayed the oil change. Since then I started using Synthetic 0W-20 and never had any complaints.
