I see this is your first post. Welcome to the forum from Pennsylvania. Where do you call home. Enjoy the forum and ride safe..I have used Castrol GTX for years with no ill effects. Was told recently that this may not be a good idea so sent Castrol an email to see if GTX meets the JASO-MA spec. This is my second gl1100 and have been told that oils have changed, will see what Castrol says and if its bad will let you know Nick
Just to set the facts straight, I am not associated with LiquiMoly and gain nothing by endorsing their product. You can use any, as you call itUltimately any oil that meets honda standards will be a good oil, just stick with the more well known brands for added security..
MOTUL MA2 10/40 is highly recommended for GL1100 with HIFLO FILTRO HF401 Oil Filter. This is in my 81 GL1100 that is reconditioned "Top Down" all to Original spec"s. Do research on these products. Resonable price for #1 product. There are other Great products but this is my choice.what is the best engine oil to use on a 82 gl1100? whats the most reliable?
