Hey all, just bought it today and looking to change the oil tomorrow. Is there any particular brand and weight I should use? Also, limited slip diff fluid. How much in a 67 10 bolt and what weight?
You'll get a lot of recommendations. Everyone has their preference. For me, I use a Napa gold filter and either Quaker State 10w-30 or equivalent conventional oil. The Napa 10w-30 is good of you can catch it on sale. You'll need a zinc additive. Either ZDDP or Lucas engine break in additive Rear axle- 80w-90 and whatever limited slip additive they have on the shelf. Do you have a suction gun to put the oil back in? I would buy three quarts. Better to have a little more than not enough! Make sure you order a new rear cover gasket.
I do not have a suction gun. I'll look for ZDDP and remember that weight of diff fluid. I'm now thinking Valvoline VR1 10w-30 and I have a napa gold filter already.

If the 430ci engine is original with unknown mileage and you are a "boulevard" cruiser you can use 10w40 from Valvoline for example. For years i am using Valvoline mineral oil 15w40 and with good results. I am not going to try anything thinner then 40 weight.
