Title: Oil weight?
Post by Jsud04 on 11/12/13 at 04:18:22

Should I stick with 10-40 or change up to a different weight?

You did not give us much information.  Where do you live, how cold is it there, how long is your ride, is the bike kept in a heated garage or left out in the cold.....

Here is some good reading for you to find the answer to your question.

Rotella T is 15-40. That's fine for the temps you are likely to encounter in Va. year round.

Rotella T6 is 5-40. Also fine but since it's synthetic it costs almost twice as much and if you change your oil every 3500 miles ( Suzuki's recommended interval) it isn't worth the extra money IMO.

So,.. if I spend the extra money for T6, I'll be spending an extra dollar a month overall to have synthetic oil.  Even though I am a social security type, I think I'll stick with T6.

Only reason to use synthetic rather than conventional oil IMO is if you plan on extending the change interval significantly. If you're dumping it every 3500 miles it aint even worth the extra buck a month as far as I'm concerned. :)

Jsud I'm in Kentucky,and ride at least a little every month year-round. I think our climates are about the same and the 15-40 Rotella T works just fine year-round.

There are two other reasons,.. and I'll admit they are not a very big deal.  (but neither is a buck a month, eh?)

1. Synthetic holds its film strength better in higher pressure and/or higher temperature situations.  Most times the operating conditions in the derated Savage motor don't come anywhere near needing this extra film strength, but for a price of taking the ex-girlfriend to McDs one time, I can afford the luxury.

2. For the folks living in colder climates that might want to start the thing up when it is really cold, T6 stays runny even at temps well below freezing.

Remember what I said, now,... these are not hugely important factors.  

I feel like splurging on T6 because the additional expense is next to nil, so it isn't much of a splurge.  

If I rode the bike for an hour or more every few days, with T6 I wouldn't change it every 3,500 miles.  I'd go for a lot longer than that.

If you flog your motor at high speed a lot T6 is a good idea for you.   T6 is also a heat proof oil, able to withstand thermal abuse much better than dino oils.

However, if you ride conservatively you don't need that function either.

So, run T6 for a year and not have to worry about overheating or abuse factors during that time, or use normal oil and change it more frequently.

Your bike, your riding style, your pick.

If someone sees their Rotella T useage increase at about 1,500 miles on it, like I did, & they swap to synth & DONT see that increase, then there is a real good demonstration of the synth holding up better to the shearing of the oil. Im Guessing it was shear causing the marked increase in use. I can picture anything else causing it,

Should I put that in my f-150 as well?

My F150 Calls for 10/40. I ran the 15/40 for a few years. The engine has close to 200,000 on it,, I reall dont know, because the speedo doesnt work right, didnt when I got it,, so, it says about 160,000,, now, how many miles have slipped by? I dunno,, anyway,, I was getting lifter clatter.
Not immediately, it took a coupla years,, was it gonna do that anyway? I dunno. I went back to 10/40. I didnt see an immediate improvement,, its still there, not sure its better.

Cold, its sposed to flow as if its the lower number, hot, its sposed to flow like the higher number, SO, its almost always getting what will behave as 40 weight, so how could it be a problem with the lfters? Im not seein it. I just decided to see if I could note an obvious difference,, I cant,,
SO, In answer to your question. Im going back to the 15/40 in the truck. Its In the lawnmower & backhoe. My mower is an MTD 2 cylinder, has a filter, so it has a pump, Its 7 years old & we have a big yard & I abused it by clearing some brush, meaning to walk thru you needed a machete. The area was about 7500 square feet, but I didnt just try to roll right thru it, I just whittled the edges. Took 3 years to win that,,
Anyway, Ive seen mowers like that crapped out, burning oil, no power in way less time.. Ive run the heck out of it & its hangin in there just fine,,truck doesnt use oil at all,,
