Straight grade oil users

[AutoMechanic]

I was using it in the Beetle for the winter because I read online multiple sources and heard from many mechanics it was better for winter since it didn’t have a winter rating well apparently that was wrong so now I just use it in my mowers.

I use 30 in one of my motorcycles. That is what it was specced for, and it's a shear factory with a wide 3 gear helical primary drive. It can also be used in my BMW motorcycle between 0 and 30 C, my riding temp zone, and used it one year with no problem. I was tempted to use it again, but as I am back to commuting on it again, it is often over 30 c when I leave work in the afternoon. Was very tempted because I can get Delvac 1330 for a good price.

Better question for YOU: why did “we/YOU” ask about straight 30 wt oil while I did not? I’ll wait for a honest answer

The only "straight grade" oil I use is 30 grade non-detergent oil, it goes in my power washer pump.

Curios on the though of the question I really like to see why people bring up unique subjects as such. 30 wt is what is ingrained in my mind when it comes to straight wt oils,,, a Freudian slip I would guess. The company I worked for for 17+ years used straight 30 in their 3 semis, the over a 500 forklift rental fleet not including the electrics and all the Ford Service vans and the company cars plus all of the contracted vehicles "we" serviced that belonged to our clients. There was never a failure of an engine . This was in the San Francisco Bay area , the head office in San Jose and branches in Burlingame Salinas and Dublin California. The 30 wt was used all year. I use 5w30 or 0w40 oil because it works all year long and allows me once a year oil changes. P/S I hope you didn't think it was too long for the response.

Good point. I grew up using 10w30, then later 5w30

When I told my dad we shouldn’t use 30 weight or any straight grade in the winter for the beetle he was like why and I explained to him and showed him this forum and he was like amazed lol.

I use 90 wt gear oil in mine.

I have a gut feeling that a straight wt oil would give better engine life with proper starting temps with equal quality base stock and additive packages but properly maintained engines usually last and last with multi viscosity oils and the winter time cold starting benefits are huge.

Use 30wt ND in the 28 Chevy doodlebug tractor. Stopped using straight weight in the air cooled maybe 10 years ago when noticing a hot drain poured out like water. The 28 runs cool with no provisions for a tstat.

I had to look up the tractor ,it is really cool

Very, very good answer CT8...

I like the history you shared here in this answer.

Hope you had a good Christmas. Good to see you on here.

I don't think monogrades have all the proper add packs for car engines since there is not huge market for them. Could be wrong.
they sell them for lawnmowers, etc.
If they sold them for cars I may try a high hths 25W25 in the summer. High hths 25 is the lowest I would go.

Many are API SN rated

 

[demarpaint]

I use 90 wt gear oil in mine.

That's interesting, mine calls for straight 30.

Yep … have a few quarts of SuperTech HD30 that’s an SN “fleet” motor oil …

I was a straight grade disciple for much of my life. I'm also old enough to remember getting a choice in bias ply or those newfangled radial tires too.

....and drum or disc brakes

 

[salesrep]

Straight grades make sense if you do not need any type of cold weather starts or controlled indoor environments.

Garelli gearbox uses non-detergent 30, summers I run Valvoline conventional straight 30 in the "Scrub" Cadet.

Nothing wrong with a good monograde. I was a farm hand for a few years in the early nineties and the fella I worked for used Exxon 30wt almost exclusively in all the trucks and equipment. I can remember working at the Texaco as a kid, and the owner had a basic lube that used bulk detergent 30wt. It was cheaper than a lube with the Havoline Supreme multi grade. I think today's monos are better than they've ever been.
