is there any other thicker oils you can run besides the polaris pure synthetic?

 

$12.90 per quart

 

[img]i/expressions/face-icon-small-happy.gif[/img] Our previous oil was 0-40,now the ps4ss is 5-50. Using thicker oil or infrequent oil changes will starve top end of lubrication and I or someone else will be changing out your flattened cam!! exhaust lobes ALWAYS ground down to nothing!!IF YOU MUST use other than Polaris, Mobil 1 makes 0-40! I've changed too many cams because of wrong oil /lack of maintenance! Hope this helps your decision!

 

If your owner's manual says 0W-40 then you better use 0W-40. If it says 2W-50 then use 2W-50. Good oil costs a lot less than a good engine. NEVER use a thicker or thinner oil. What brand you buy is up to you, but make sure it's a full synthetic of the right <u>weight</u> and <u>service grade</u>. If your owner's manual says API certified SH oil, and you don't use SH you're just asking for trouble.

When the manual warns of SERIOUS ENGINE DAMAGE, I listen. IMO, everyone else should too, unless they can afford to constantly buy new engines. I can't, but I have enough money for oil.

 

i agree that using the right oil will make the engine last longer. sometimes being cheap wont give good long time results. always use the fully synth. oil. imo.
