Lucas Syn 20w50.

Just put Lucas Syn 20-50 cycle oil in my engine last week and this is the quietest oil yet. So far I am impressed! It dosent seem like too many people use it for some reason but so far its my fav.

Probably do to the availability at a local level. Mobil 1 seems to be at most of the auto parts stores.

I picked it up at O'riellys auto parts, They all carry it.

No doubt Lucas Syn 20-50 is a good product.
Few things to be careful of judging oil by sounds is miss leading.
M1 will cause a bit more engine noise (compared to standard oils) but hard to find a better engine oil.
Today's engines need oils that flow better the old days of running a thicker oil to quiet things down just do not work anymore.
I run Spectro only because I like the company, I have often noted it does have less upper engine noise and seems to hold a slightly higher oil pressure when hot.
Of course none of this makes it a better oil just a bit different.
One thing I would avoid is any of the oil or gear lube additives they offer. I have seen some test that show it causing sever foaming in motorcycle engines and gear boxes.

I hear ya on the additives. I dont beleive in using them, they simply mask a problem that needs fixing.

Ran Lucas Syn 20W-50 in my Sporty, worked just fine, but I change my oil every 3,000 miles, so reason was for cost...O-Reily' price at $6.99 everyday, is very good and is rated for use in V-Twins...Mobil 1 V-Twin is $10.95 everyday (may find it on sale for about $2 off) !

i have run mobil 1 20w-50 v-twin for 3 years now no problems very happy but it has crossed my mind a few times to give lucas full syn 20w-50 a try might do that next oil change i know AMS oil is a good product but there advertising tactics ....i don't care for...so there oil will never rest in my crank case

i've used the lucas 20w-50 and so far no big problem. but i've found out, in "stop n go traffic", the knocking "tic tic tic" sound comes around if i open the throttle abruptly, i'd assume that happens because the engine temp is high not getting enough air to cool down in traffic jam (climate is also warm). But if i open gas gently, no knocking. That knocking also happened when i used hd sae50.

is that because of the high temp or the oil?

Tobaman, are you running premium gas, and are you running EFI (w/fueler) or Carb (w/enriched jetting)? May also want to check the plugs and possibly use decarboning combustion chambers using H20...

High temps. The knocking is most probably detonation from high cylinder temps.
Only does it in stop-n-go, so engine gets hot and knocks.

yep only in traffic jams. after getting out the traffic jams, i kinda have to open the gas slowly to reach higher speed to get more air so that the engine gets air. usually after getting cooled down, no more knockings.
