6.5hp 196cc Gasoline Engine Oil Help

[VirtualGod]

Hi guys, I don't know anything about those oils.
I have some 5w-30 oil but jug says it's for diesel engines.
But you know my engine is gasoline so can I use?
I got my engine and manual says 5w-30 good for cold days. (0 - -20 and lower weather temperature.)

So should I use or not?

It says this oil is for diesel engines.

I would not. Too thin in warmer temps.

 

[Bbqjoe]

I suppose any oil is better than no oil.
We have seen someone here use pancake syrup, and it's still better than no oil.

Beer, is not a good choice though.

Thank you for your reply Weather temperature is about 30-37C here in summer. But in winters, around 5- - -5C. I mean can I use 5w30 temporarily in summer? I won't use, just gonna test the engine. Then If I can I will change the oil.

Lol

Then I will fill it up?

If the manual says 5w30, then use 5w30. Is that 0-20 degrees in Celcius?

Diesel oil basically just has more detergents in it than gasoline oils, and most of the 5w30 diesel oils out there are "all fleet" oils.

Yes 0-20 degrees in Celcius.

So should I use? I will use it for just once to try the engine. Then I will change the oil or if weather is cold I can use the 5w-30 one right?

That's t-shirt weather

Go ahead And use it dout anything bad will happen...

Well 20°c is what... 68°f, so you'd probably be borderline in summertime.

What does it recommend, a straight 30 for warmer weather?

The 5w30 will be fine for testing purposes. I wouldn't ride it hard for hours on end at 90°f, but it'd be fine for occasional use.

Straight 30 and 10w30 both recommended.
There is 3 recommended oils and 5w30 is the last one. (0 - -20C)
Thank you again I'm just gonna start it to see how it sounds lol.

 

[Bbqjoe]

Why don'y you just go get a quart of the right oil?

Oh wait. Are you grounded again?
What did you do this time?

 

[Hellion]

5W-30 is FINE and oil recommended for diesels is also FINE.

I suppose though, that since we're running air cooled engines here by and large that we could run heavier oils;

5W-40
10W-40
15W-40
20W-50...

What if I just took my grease gun and pumped it full?

I remember a thread on an auto forum... Somebody told this kid thicker oils lubricate better (which is true to an extent) so he filled his engine with 80/90 gear oil and it blew up.

SAE seems still confusing to most people...

The "winter" denomination (and yes, W means winter)
is pretty straight forward and easy to remember (for all but americans tbh...)

0°C (freezing water for you fahrenheit users)

Here's how:
20W oil is just liquid enough to be pumped at -20°C (SAE J 300)
and now follow the steps in opposite direction...
15W oil -> -25°C
10W oil -> -30°C
5W oil -> -35°C
0W oil -> -40°C
and of course :
25W -> -15°C
30W -> -10°C etc...

the high temp scale works differently..
it denotes the viscosity of an oil at a fixed (high'ish) temperature namely 100°C (boiling water)
in terms of flow rate
thinnest:
SAE 16 is 5,6 mm²/s
SAE 20 is 6,9 mm²/s
SAE 30 is 9,3 mm²/s
SAE 40 is 12,5 mm²/s
SAE 50 is 16,3 mm²/s
thickest oil
SAE 60 with 21,9 mm²/s

you can take the winter rating as an indicator of ambient temperature.
you cannot do the same with the "summer" rating.. it's pointless...
a combustion engine running is ALWAYS way hotter than the ambient temperature,
so there wouldn't be any point.

but a SAE 30 rating (right part of the number) has always the same min rating (9.3 mm²/s)
no matter what the left side of the number denotes..
it can be better (thicker) but never worse.

so if the manual calls for 10W-30 and you get 5W-30 you will be fine, there will be next to no difference in summer and it only stays liquid enough to start your engine when you left it outside in the winter... in siberia!

I use 15w40 Rotella-T diesel oil year round in my small engines and especially for breaking in a new engine. Diesel oil still has the zinc in it which is great for flat tappet type engines.
I guess I'm the odd ball here !

 

[Hellion]

I use Rotella T6 5W-40 in my turbo Saab (whoops)...but I don't have it in sufficient quantities for anything else. But yeah, the Shell Rotellas are well-respected oils. I would not hesitate to recommend them for anything non-diesel.

However this simple statement comes to mind:

Any decent grade of oil within the required viscosity range will do the job more than adequately.

 

[Bbqjoe]

You know, there is still lot of things that FHB missed on.
Vegetable oil, olive oil, lard, baby oil, Emu oil....

Thank you Gonna fill it up when i get gasoline.
