![]() Remember, too high oil pressure is no good, it just means oil is having a problem flowing through the engine (like blood pressure) :o) Its a heavy robust oil, also Mobile 1 and Amsoil 20/50 motorcycle oil is too.Īnyway, hard to know, only way is for him to try others until he see's an oil pressure he likes. Honestly, I think he would be better off with the HD Conventional 20/50 oil if looking to increase oil pressure. Using a 15/40 HDEO or any other 40 oil would be a disaster if looking to increase oil pressure, he wants a 50 for sure. I do use an 15/50 HDEO Mystik JT8 but will not be readily available anyplace in the country, I mail order mine but Rural King and other stores like that carry it.Ĭitgo makes it, same as they make HD oil. ![]() However we are not talking about a 14 or later bike. I guess what I'm saying is it would be misleading for me to say go with this oil to solve low oil pressure issues because there is a bit more to rule out before steering a person correctly.ĪS far as using a HDEO, well, he is wrong on that, all he has to do is read 2014 touring owners manual and later owners manual, as it states to use an HDEO oi if Harley Oil not available, no other type of oil is mentioned as a substitute other then an HDEO. Age or mileage or checking into pressure switch and oil pump gap with more quantitative measuring tools. Things like oil filter used may have also been coincidently attributed to low oil pressure. If this happened to me, I would be hesitant to blame the oil unless i can turn the problem on/off repeatedly and not occurring intermittently. I'm sure you can return just about anything with a valid receipt within a store's policy time period and typically store credit without receipt less sales tax and sometimes they'll credit the person at sales price regardless to deter fraudulent returns.īut my reply is more of an inquiry into how it was determined that a syn oil vs. He said he bought a rather big supply of Valvoline 20W50, and he's now wondering if he can return the unused bottles and get a refund. I'm not sure if he'll try another synthetic right now. I've also noticed Mobil 1 V-twin gets mentioned a lot from HD riders. Mobil 1 V-twin oil has a pretty high rating and positive feedback for the twin cam 88 motor owners including myself. I purchased the Mobil 1 V-twin oil during the month of March +/- month when bike season is in full swing and places like Autozone, Advance autoparts "always" has sales for motorcycle specific oils for ~$2 off/at or reduced oil change packages so at least you can stock up. Thanks in advance.įor my Fatboy, I used the HD360 during the warranty period and then the Mobil 1 V-twin 20w50. I'm a Trucker, and I've told him I've read many posts from HD Riders who use 15W40 HDEOs in their motors, but he's concerned the higher engine temperatures in HD motors might not be a good idea for a 15W40 HDEO. I see it on Walmart shelves across the country. He's a believer in frequent oil and oil filter changes, so I'm guessing a quality conventional 20W50 would work well(?) The first conventional 20W50 that comes to mind for me is Castrol GTX Ultraclean. Widespread availability is important to him, so I'm trying to find a brand of 20W50 that can easily be found on the shelves at Walmart, Autozone, etc. My brother told me the price per quart on it, and I'm wondering if simply using a name brand conventional 20W50 would offer equal protection and performance at a lower price per quart. He talked with a Harley mechanic and he recommended using HD's conventional 20W50. He recently tried Valvoline synthetic 20W50, because it's cheaper and can be easily found while he's traveling, but he said his oil pressures in both motors ran very low. ![]() I'm actually asking a question for my older brother who owns a 100th Anniversary Electra Glide and a Road King. Models 1975 and later use Dot 5 brake fluid.I searched a bit and couldn't find an answer. Shovelhead models from 1966 to 1975 use Dot 3 brake fluid. HD Primary Chaincase is used in the primary chaincase. All shovelhead models 1970 and later use HD Type B fork oil. HD Hydra-Glide fork oil is for 1966 to 1969 models. Harley-Davidson makes two types of fork oil for shovelheads. The transmission uses 1.5 pints of HD transmission lubricant, although many people use 75w90 gear oil mixed 3-to-1 with Lucas oil. Harley-Davidson recommends 4 quarts of SAE 50 or 60 engine oil in all 1966 through 1984 shovelheads. The primary lubricant should be changed at 5,000-mile intervals, the transmission oil every 10,000 miles and the the fork oil every 20,000 miles. The official maintenance recommendation is to change engine oil every 5,000 miles, but changing the oil at 2,500 miles is a good idea for an older shovelhead. That keeps the engine and other moving components lubricated and operating efficiently. Motorcycles need their main fluids changed at regular intervals. ![]()
