Engine Oil Poll

[bluesmanjesse]

OK, so all the other forums I'm a part of have a thread about engine oil opinions.

First off do you use Synthetic or conventional oil?

Secondly what brand do you use and why?

[Jfer]

Synthetic----Mobil one 4T racing oil 10W40---- Oil is the life blood of the engine, and it is readily available at Walmart or auto parts store in my area.

amsoil synthetic preferibly -- but first oil change in my grizzly was honda fully synthetic andthats alls they had at the time and i needed an oil change -- second will be with yamalube synthetic -- but after that i will make it a point to use amsoil -- i use it in my 1800cc m109 and never had any issues -- i just like it -- makes things quiet and smooth. still thick and clean when i change it out.

you can argue what types of oil for days -- people will pull statistics showing breakdown and all that other bull -- try differant ones and use what you like .. go by what a friend tells you --

Im runnin Amsoil mainly because of the great deal I got here through our sponsors. they were very responsive and helpful. they have been kinda MIA latley...
I have it in the engine and diffs. My truck and car are also running it, Ive had no problems with it in the desert heat. We'll see when it gets cold but I dont forsee problems there either.

An interesting and often misunderstood fact about oil,it actually gets thicker as it ages/with use. Conventional oil has additives in it to make it thinner upon startup,it is actually like a 250wt naturally when cold,as it ages those additives break down and it takes longer to thin out when your engine warms up so your engine wears more with old oil in it,esp during the first few minutes of operation.

Conversley Synthetic oil starts with a base oil that is already thin, a true 30wt per se. So theoretically you could run the same synthetic forever and just change your filter periodically to filter out contaminates.

The point is you want your oil thin as soon as possible after startup and you want it to end up the right thin-ness at operating temp.

Being a mechanic I love Valvoline products always have always will! With that said sythetic has its advantages but when you are strapped for cash and as oten as I change oil in the Grizz there is nothing wrong with using dyno oil! FWIW My choice for a synthetic is Redline.

Maxima synthetic.

I have been running amsoil in my dirtbike and I LOVE IT

Another little tip,do not mix Synthetics,they don't play well together,if you are in a pinch put regular conventional oil in the synthetic to top it off until you can do an oil change.

I wish Valvoline would come out with a full synthetic for atv's. I'm using the full syn. high mileage in my truck and van and it works great but I've been using Amsoil or Yamalube full syn. in the wheeler.
