Use 10w 40 instead?

I'm doing the first oil change myself. I've read up on that 40 rating sticks to the parts better than the 30 at high temp. It's pretty hot where I live especially in the summer. So I used 10w 40 instead of 10w30. There's no harm to the engine right?

I have a 2016 cbr500r

It's fine. I use Rotella T6. A lot of people do.

Yep, it’s fine. Many or most dealers seem to just use 10w40, actually.
+1 for Rotella

2013 CBR500R - probably up for sale soon - OK, NOT!
2006 GSX-R 750 - track only
1984 CB700SC - hopefully running again soon, then maybe up for sale
2012 CBR250R - Sold!

A suggestion. For future oil changes do it more often than the manual recommends. I do oil & filter every 4000mi.

Ride like your life depends on it.

Agree. I do oil every 2000-2500 miles. Filter every other oil change. I ride hard. Oil gets frothy after 2500 miles with my riding style, especially during summer months.

Hi, I can confirm my first service by the dealer, for my 2018 CBR500R, they used 4T(semi-Synthectic) 10W-40 oil.
Its
always best to keep the same brand and type available for small top ups between oil changes.

In heavy industry, the quickest way to increase wear in parts is to not have clean area / clean oil/ clean equipment. Important to make sure if you keep a bulk (4-5 litre oil container) that it and any funnel you use are spotlessly clean when you are doing to ups. Contaminants introduced during top ups and oil changes are always a risk one needs to take precautions against.

I use Honda oil. But I’ve also used 10w-40 as well with no problems.

Many places in Au use 10W40 claiming bcs it is hot here. I use Honda 10W30 bcs thatís what Honda recommend.

I had one service report say they used 10W50. They claimed it was a typo. I dumped that out and now do all my oil changes myself.

Marxious - congrats on the bike, and welcome to the forum, and congrats on your CBR. They're great bike. A lot of us are on the fence about "upgrading". (going to a bigger bike) I've been there and I may go there again before I get too old, but for now, it's hard to justify and would cost me dearly in fuel consumption.

One thing that's pretty regular in internet motorcycle or automotive fora is "oil threads". But we just can't resist chiming in every time.

Here are my thoughts:

Use 10W-30 synthetic. Being only 30 weight when hot, it makes for less internal friction and better fuel economy. Temperature is not a concern, since it is synthetic, it is much more resistant to thermal breakdown than conventional oil, and I will go the full 8,000 miles without any worry or extra work.

It's not as common as 10W-30 without friction modifiers, but it's still easily found online.

It would be all too easy for Honda engineers to recommend more frequent oil changes and thus sell more oil and filters and service.
