Posted by Geo-TH,In on February 01, 2015 at 06:42:08 from (184.16.165.4):

The hydraulics on my terramite calls for motor oil, 10w40, not hydraulic oil. So using hyd oil is a mute discussion here. I'm following manufacturer�s recommendation.

Today Menards has Quaker state full synthetic on sale for $2.99 after a $2 rebate. They don't have 10w40 synthetic. Menards rebates is a no brainier for me, but I'm sure some hate it. Menards rebate is another mute issue for me.

The real issue: Is 10w30 full synthetic be better than 10w40 non synthetic? 10 w stands for 10 w in winter and the other number is the weight when it warms up. 15w is too much for my winter. I allow about 10-15 minutes for my hyd to warm up before using. 10w when cold, makes the power steering very stiff.

Keep in mind, synthetic oil can get hotter before it breaks down and my regular motor oil is breaking down, smelling burnt and turning dark. Oil breaks down under pressure and temp. I need 5 gallons. $12/gallon synthetic is a bargain.

Will 30 be enough when it calls for 40?

Today's Featured Article - Restoration Story: 1929 McCormick-Deering 10-20 - by Randal Simmon. On July 4th 1998 my dad and I was sitting on the front porch when he said that he was going to sell his two 10-20's to a junk man. He said that the junk man was going to give him $500 for both of them but he hadn't received the money for them yet. So I went into the house and wrote him a check for $500 and bought them myself and said now they are mine. He had bought them about five years before thinking that he was going to restore them himself. After five years sitting in the barn, he changed h ... [Read Article]
