Vanguard 18 HP Oil

[fulleraviation]

Hey Guys,

Any recommendation on oil for a Vanguard 18 HP Engine? I now have about 10 hours and was going to do the first oil change.

Thanks,
Rutledge

I use a basic SAE 30W oil but a lot of guys run synthetic also. Briggs actually suggests several different oils based upon the temperatures in your area and they have them in this convenient chart. The synthetic 5W-30 seems to cover all aspects:

I'm sure others will chime in as well.

I think straight weights are a good idea, because the polymers that make multiviscosity oil work, break down and the oil thins. I run snythetic 10-30 but change it very often.

I have a couple part #s for non briggs filters if anyone wants them.

Rodger,

I would like the part numbers for the non-Briggs filters when you have the chance.

Walmart 4967 I think this is a cheap, short Fram. Never seen it or used it, but others do.

I use a bosch 3330 a mid grade 5-6$ filter, also longer.

I would use a purolator Pure One if I took the time to cross # it. Napa and Wix good also.

That Vanguard will last forever if you change the oil and filter often. When I went through mine, it still had the cross hatch in the cylinders at around 175 hours.

Hi Everyone,
Warrning about oil filters on the Vangaurd. If you use a aftermarket oil filter be sure it has the check valve inside it. My Briggs rep. has told me that they have had Vangaurd engines fail early because the customer used oil filters that fit and look the same but do not have the check valve inside. For the few bucks you save by buying a aftermarket filter it is not worth the high price to replace the engine. Matt
