I have a cb500 four and wondered what the best oil to use, I'm in the uk

ThatThere are lots of oil threads and it is a common "flamebait" topic that comes up when people's strong opinions are voiced.

Look at this thread and determine if you want to use one of the recommended MOTORCYCLE oils which are discussed. Individuals have discussed what they have observed after switching to a better oil with a good zinc package.
AVOID energy conserving and friction modifier oils as they are bad for our pushrod sohc motors. After SF the zinc started dropping for all oils except those for motorcycles BUT not all motor cycle oils have the zinc and phosphorus and other additives that help our motors not wear quickly. So, read the thread, take notes for those you can easily get, belray and motul come to mind. Spectro being a us oil make. Through Amazon you can get just about anything if you wish to pay the price to get it to you...

Good luck
and ask questions about specifics and it is better...

In the UK, the Motul and Castrol XLR have a good reputation for these engines.

Got to looking for Spectro and found Dennis Kirk sells a good variety of Spectro products by the liter or case. Free shipping on orders over $89.

RAFster122s · « **Reply #82 on:** June 17, 2018, 05:28:46 PM »

Does a gallon or case of oil have to ship under a hazmat label? If so, they may have it shipped free except the up charge on the hazmat label...would be nice to think it would ship free. Buy 90 of oil to protect against future price increases. Let's not debate current and future value of money.

Marks78 · « **Reply #83 on:** June 18, 2018, 10:18:38 AM »

Just ordered a case from Dennis Kirk and there was no mention of hazmat shipping charges. They did say it could not be shipped via Air mail. Shipping was free for over $89 order. Supposed to arrive at my place this Thursday.

Im going to stick up for Rotella T4 and ZDDP plus. Ken at Cycle X recommended the ZDDP to be added to a gallon of Rotella. I am running this combination in my race bike this year and so far no shifting issues or clutch slipping. Comes out to about $23 for an oil change plus filter. I can change it more often now (race bike and all) and not have the wallet hurt nearly as bad.

Yeah, no kidding:3 years ago I bought a case of the BelRay EXL at the peak of the prices, $32 per gallon alone!

I have been reading this topic and still I am not sure how much additive to put in my oil... I am running Pennzoil high millage 10w-30. I do not have alot of miles on the bike, but I get a crunch in shifting which is what led me here. zddp+ seems to be the choice on here, but is one bottle (4oz) to much?

Thanks in advance

Just bought your book Hondaman! Thanks for all the effort!

Is that car oil? If so get rid of it. I add one small bottle of zinc to each gallon.

That oil is FAR too light for any of these SOHC4 engines. If it is the 750, use 20w50 unless it's wintertime. You can sneak by for short-haul in-town riding on the smaller Fours with 15w40 or 20w40 diesel oils, but even 10w40 is too light for summer use in any of these bikes.

Hondaman what is your opinion on Rotella T6 for a 550/500 4?

I don't know what the T6 type is?

slikwilli420 · « **Reply #91 on:** July 26, 2018, 11:55:28 AM »

T6 is the full synthetic version to T4. Run the T4 as its a bit cheaper, still a great oil. I know guys like expensive motorcycle oils but I really dont think its necessary. I change my oil (especially with a still very new engine) after every race weekend. The Rotella has the required specs for our engines, and boosted with more zinc makes for a great recipe.

Certainly the "more zinc" part is a good thing for ours: I haven't yet been able to keep the synthetics inside my 750 yet(!) because it seeps out thru the paper gaskets after a while. It washes off pretty easily, though.

Our member Ofreen has been using the Golden Spectro synthetic for a long time: he only has a small weep somewhere that comes and goes. When I used the synthetics in mine, it made puddles under it, though, mostly from the left side as it was parked, and the cam coverall around. It sure was smooth-shifting, though!

Mark,

Have you tried Kenny's gaskets from CycleX? Coated metal. I just picked up a bunch as I needed a valve cover replacement.

Just a small correction. Golden Spectro is no doubt fine oil, but I have been using the Spectro Heavy Duty 20w50 all these years.

Somehow Greg has good results with the VTwin oriented Spectro. That is contrary to conventional wisdom that the VTwin motor oil additives aren't ideal for the 4 stroke motors.

Fixed that for you, Greg.

Nope, haven't seen those in real life yet. If it's a head gasket, watch the thickness? Or, a base gasket, same thing...
