Hi guys i am fairly new here and need some advice. I have a 1973 international scout II with 345 V8 rebuilt motor 10 years ago but only 15,000 miles on the motor. It only gets run a few times per year. I was using castrol 10w-30 gtx synblend and was very happy with the results. However i am currently not employed and would like to save some money. The Synblend runs almost $7.00 per quart at oreillys auto the (only place I can find it). However at walmart I can get the high mileage castrol gtx synblend for only $17.00 for 5 quarts. That is quite a nice savings! But I don't want to ruin the motor in any way as it does not have high miles..... I was thinking since it is a older style motor the tolerances aren't as tight as new motors so the high mileage oil might work well in it...... Do U Guys have any opinions experiences, I would appreciate it...
Thanks,
Brandon
