What oil do YOU use?

Out of curiosity, I was curious as to what brand and viscosity everybody ran in their engines, or what they prefer.

Me personally, I like Pennzoil 5w30. Its more expensive though so I usually settle for Parts Master 5w30 or 10w30. I plan on running full Synthetic in everything of mine soon.

Full Synth 5w50. On modern stuff.

Single grade (mineral) 30w on the old deere.

Earlier I preferred Pennzoil on bike engines, but now I really like Castrol. But I don't really have a reason for liking one over another, same smelly stuff in all +- some additives with strange names.

Isn't it with oil like with Toothpaste? same shiz different wrapping

I use royle purple 5 w30 syn motor oil.

any that i find, lol, it loses it so it dont matter anyway, lol but im using havoline supreme 10w-40, i found it might as well use it

pennzoil or valvoline 10w-30

I got a 5 gallon bucket of heavy duty 10w30 a while back.

It was a freebie, so I run it in everything that isn't critical.

on my lawn tractors ive never changed the oil:P on my car i use Rotella T 15w-40, on my Baja Warrior i use Royal Purple 10w-30, and when i change the oil on my parents vehicles i use normally cheaper Oil not the cheapest brand of oil but conventional Oil, Normally Castrol or Quaker State, depends if one is on sale, normally a popular brand of Oil that i have heard people using before that is Cheapest in price.

I use the cheapest kind I can find. Either Autozone special or Advance Auto. 10W-40

super tec hd 30 from wall mart

I use whatever I can find

i use castrol 30 weight

Valvoline VR1 Racing Oil SAE 50

50w*

Amen Brotha!

i run either mobil one 10w30, or quaker state 10w30 synthetic

In some larger engines, over 500cc/30cu in or about 17HP+, I prefer to run Shell Rotella T Triple protection 15w-40 Diesel engine oil. Yeah yeah it says diesel on the bottle... :roll:it's an extreme pressure engine oil for anything run long and hard, as most ATLTs are. Smaller motors [under 500cc/30cu in] should just go with 10w-30 mineral or synthetic, or just straight 30 weight oil if you only run it in the summer. If in doubt, check your manual or a sticker on your engine. Most briggs air filter covers will tell you what oil to use and when. General rule is 10w-30 summer and 5w-30 winter. Oh, I havent used the Rotella T in the winter, and I wouldn't advise it as these air cooled engines run colder when the ambient air is cooler, so the diesel oil is probably too thick to get where it needs to be and you could prematurely wear out your engine.

p.s. the first two digits in a briggs and stratton model number are its cubic inch displacement i.e. model 90202 lawn mower engine is 9 cubes, or 148cc, and a model 190502 snow blower is 19 cubes or 311cc.

i run valvoline non-detergent SAE 30 all year round, winter and all Have to run a lighter oil in winter... Just so you know jack

You also live in West Virginia. The winters down the mid-east here arent as harsh as the northernmost states.

i ran castrol 10w30 and drained it when i found metal shavings in it and changed immediately back to royal purple 10w30 no shavings since. none before. i usually run mobile-1 because ive trusted it for years since i had my first car. never had problems with it

Well said... Canadian, eh?

I used mobile1 high mileage (lol) 5w-30, its just what I had. Thanks motorized for what to use too

I use 20w50 with 1/4 lucas oil treatment. I use this on everything I own that has an engine.

Interesting. I would consider this too thick for our industrial/stationary/tractor engines. May I ask why you would select something with such a high viscosity when it is clearly contraindicated by all the manufacturers' documentation?

My uncle is a master mechanic and works on everything from cars and light trucks to yachts and cruise ship. He has used this 20w50 and the lucas oil treatment for about twenty years now. He got me onto it about 5 years ago and I said the same thing, thw viscosity has got to be too high! But after 5 years im a believer. I use it in my wifes mini van my truck all my mowers. I use to commute a hundred and twenty miles a day for work and I drove a saturn vue with a 2.2L 4cyl. It called for 5w20 I always used 20w50 with the lucas oil treatment. The car had 322k miles when I stopped driving it. I sold it to a local mechanic who later told me the engine still had near factory compression! I have never had and issue starting any of my motors even in the coldest days of winter.

That's amazing, and near-unbelieveable. But hey- If it works for ya, it works for ya, right? And why mess with what works?
