Just got 2 of these, going back for another 2 tomorrow - cheapest I have ever seen it

Castrol semi-synth 15w40

should get 16 briggs/honda 600ml changes out of 2 bottles - $1.5 per oil change is good enough for me

Also Bought a 5l Penrite bar oil at SCA for $25 on clearance - normally 44 at repco. Good for the saw and air filters
Penrite bar oil

They do have castrol 30w on clearance for $4 per l, but not much stock around
