The previous owner always used Mobil 1. Do I have to stick with Mobil 1 and do i have to stick with synthetic. If there are consequences, I'd like to hear them.

Its only 47000 miles on the bike.

Thanks

Rob

HI:

You shouldget lots of opinionshere on this. What I have readon car engines:
If you use synthetic continuously, you're fine. If you change to non-synthetic, it was advised notto switch back to synthetic. It was not clear as to why. Just stating what I have read.
Meself: Use Shell Rotella 10-40 synthetic from Wally World [I believe it's a blend and not full synthetic; is approx. $21 bucks per gallon, locally]. Am happy with it;not planning to change. Have used it for last 3 years; so do many other Wing owners in my sidecar club. My two cents. TTFN.....Old Tom in NH
P.S. Forgot; Sorry: Rotella I usecomes in BLUE jug

You and I are in similar situations. When I got my 1500 at 69k I was told it had always been on Mobil-1. I found the Mobil-1 was fine with my ride but I wanted to try others.
So I bought into the GWRRA coolaid for Rotella-T blue jug and tried it for a while.
Hated it.
Later found my way to Chevron Delo-400 and found it worked very much like the Mobil-1 had. Been with it ever since and happy.

I see no reason why going back and forth between Syn and Dyno willy nilly should make any significant difference, if at all.

Sure wouldn't keep me from doing it.

The only issue that I have ever heard when switching back and forth, is that the "dino" oil has more "light end" solvent that can soften/swell the rubber hence the "dooms-day" adage that going back to syn will shrink that seals and the engine may leak oil.... If you seals are in good shape, this should not be an issue, and I agree with Rudy.. use what you want... it is not likely that you will see anything...

Hi Redbear,

In your owners manual there are parameters given for motor oil.

Any modern oil probably exceeds those parameters.

In a word, no. Shouldn't matter if your change from one to another. I've been using DELO 400 15W40 in just about everything I own for years, it's a good petroleum base oil. My 1200 SEI had Amsoil synthetic in it when I bought it but it didn't complain when I changed it to DELO. One other bike I had in my shop came in with Mobil synthetic. It went out with DELO dino stuff. The new owner hadn't had a problem by the time I left Tacoma and gave up the shop. He hadn't had any problems after three years and he's still using dino oil.

I greatly appreciate the input, thanks.





Also I came across Bob is the Oil Guy web site and it seems to confirm or agree with opinions here. Thanks again.

You can clearly switch back and forth at will. I use the Shell Rotella T Synthetic, which is an excellent Group 3 oil and has a good additive mix. Mobil 1 is excellent oil, however, and if its been used before with good results, why change?
I have used DELO in my boat diesel for years and it has worked well.

The advice that you can't go back to dino oil is BS and all from the dealers who want to get your $$$$ in their hands.

Synthetic in a motorcycle is a waste of $$$ because it will get dirty just as fast as dino oil and should be changed out at the same mileage figure anyway.

It has been said before, you cannot justify (cost wise) using synthetic oils unless you have a very good bypass oil filter that will keep the dirt out of the oil.

Diesel rigs use bypass oil filters, they can go a very long time without changing oil. Just filters and make up oil added. I know of some trucking companies that never change out the oil, ever... They just replace the bypass filters and use oil analysis to watch for problems.

Maybe I missed something on the Shell Rotella,I look and could not find it in the 10/40 as papasmurf stated.
What I put in is the 15/40 Rotella in a white jug,yes the Wife picked it up from walley world for 11 a gallon,is this the stuff you guys are speaking of running?
I sure do hope so.......

Yup, a very good oil.. another favorite (that I like better) is the Delo 400 15W40.. doesn't seem to thin out quite as quickly as the Rotella.. (next change, try it?? and give your opinion??)
