my valve train is making alitle more noise then usual,,,tensioners are 20,000 old,,,brand new lifters,,,,,my local dealership said with my milieage(my motor might be getting out of spec??)...what does that mean??...thought these motors go for like 150,000 miles with tensioner changouts every 30,000 or so.....definetly is louder........is this (exessive milieage??).......motor exchange program time??....any thoughts or opions would be apreciated,,,,headpan

Increased upper end noise could be caused by a number of things such as worn rocker bushings and excessive rocker end clearance, etc. Some top end noise is actually transmitted to the top from noises in the timing chest and those would concern me the most. If the noise is actually becoming louder than normal, I would be pulling the timing cover to check the cam bearings very soon. If you are describing the '01 model, I would have it off before I rode it at all since the rear outer cam bearing (if it hasn't been upgraded) is a ball bearing and was found to be inadequate to carry the cam and its driven sprocket load. The failure of this bearing will do great harm!

I've heard that a TC over 50,000 should go to a single viscosity oil for the rest of its serviceable life - 150,000mi. But I personally am not so certain of this. Multi viscosity oil is a good thing, but I have gone to Redline 20W60 in my older bikes, and sometimes sneak a half qt of 60W in my newer TC's.

i heard it was not a good idea to mix viscositys,,,,,mobil-1 v-twin with 28 oz. of lucas additive is what is in her since 20,000 miles

i heard it was not a good idea to mix viscositys,,,,,

You mean like 20W50?

motor exchange program time??....any thoughts or opions would be apreciated,,,,headpan

Time for a nice size crate motor.  

[HEADPAN62]

I dunno if a big inch crate motor is for me ,I use my glide to tour ,so I'd like to keep my reliability,,and yeah mobil-1 is a 20-50- Wt.

[HEADPAN62]

no, i heard dont mix 20-50 with 50 or 60 wt...either run one or the other,,

[SE08RK]

no, i heard dont mix 20-50 with 50 or 60 wt...either run one or the other,,

So it's OK for the oil company to mix it but I can't?

It wouldn't need to be a monster motor. I like a square motor as the vibration is slightly less. Anywhere from a 100" to a 110" is plenty to move nicely up the road. My 124" after awhile will have you seeing multiple lanes due to the vibration.

dont know anything about oil Co's. and how they do things,,just heard from more then I source,,(dont mix viscositys)..I did'nt ask questions,,,it was easy enough and a piece of mind to take their advice.....Puzzled,,,I would most likely try to stay 95 inches,,,,plenty of highway pull and passing ability for me,,,,,well see,,,did s&s motors for 19 years on my softail,,,,2 --93 inch motors,first one i got about 40,000 b/4 the crank pin took a dump,,,my stock 80 incher,,,,about 100,000 b/4 I replaced her and she was still going like the energizer bunny!!

Here ya go HeadPan62,

From the Chevron.com site:
"Can I mix different viscosity grades of motor oils?"
"Yes. It is always advisable to not mix motor oil brands, however, different viscosity grades of the same brand motor oil are compatible. Be aware that mixing viscosity grades will turn out a product that is different in viscosity than either what was originally in the engine or what was added."

From Shell.ca:
"If you mix viscosity grades such as a 5W30 low-viscosity oil and a 10W40 higher-viscosity oil, it is reasonable to expect that the resulting product will have viscosity characteristics which are thicker than the 5W30, but thinner than the 10W40. This change does not reflect incompatibility - it's simply a re-balancing of the viscosity characteristics. In all other ways, the product should work as expected. But there's absolutely no danger about incompatibility resulting from mixing engine oils," Miller says. "We've tested all of our grades and brands, and we haven't observed any problems."

From Mobil1.com:
"For our customers to choose a viscosity grade, we recommend they follow the engine manufacturer's recommendations as indicated in their owner's manual. There is no need to mix two Mobil 1 viscosity grades when one will do; however, we see no problem mixing different SAE grades of Mobil 1 Tri-Synthetic series motor oils."

Now we both know for sure.
