Engine oil VALVOLINE or OEM Honda

Quaker State oil is recommended in the Hyundai manual but you can absolutely use other brand too , i have used Mobil 1 / Vavoline / Castrol and Pezoil the end i picked Valvoline high mileage Synthetic oil the best of all all other brand the oil burn brown quickly

I used vavoline for my second oil change and so far so good

20w 50 Valvoline VR1 is all I use. It’s expensive but because the gearbox and engine use the same oil you need a high zinc oil and VR1 is the best out there in my opinion.

I run valvoline motorcycle 20w50 in the primary and crankcase and valvoline 75w140 diff in the trans.

I use Valvoline 20W 50 VR1 racing oil. It’s got a high magnesium content so well suited for the gearbox.

If you want brand recommendation choose Valvoline Extended Protection 5w-20 every 4k miles.

Cummins uses Valvoline premium blue.

Similar with my Audi but with Valvoline.

This weekend, the oil that's in it is coming out (it's clean) and Valvoline Restore and Protect is going in. Rationale is there will undoubtedly be deposits on the pistons, in the piston ring grooves and ring lands.

I have run the 5w-40 and stuff every day here in utah and it works fine on 300-400 bhp setups. If you are going to the strip or the dyno and going for probably 450-500 crank I would probably grab that gold top mobil one 15w-50. I would also use that for any road racing where the engine oil gets really thinned out from heat. It's also cheap at wal mart I believe. Over at 575-600 bhp we lost a main bearing when doing endurance testing on valve springs with the 5w-40 and very reasonable oil temps. It didn't really catastrophically fail, but was on it's way to it when we tore it down. Have since switched to VR1 20w-50, and the problem so far appears to be cured. That stuff will carry way more load then the thinner oils- the catch is that it's absolute sludge until warmed up. Yet another one of the barriers to extreme power "street" cars I suppose. I'm keeping an eye on it to see if we have a solution. If that doesn't fix it, the problem may be aeration of the oil- we were running at 7500+ for pretty long periods. So basically now the oiling system is a major focus of R&D for us. The oil pressure was never out of the ordinary- although it does start falling once past about 7500 rpms which is also not great.
