Hi Laurie, There is absolutely no risk or safety reduction in going to a straight mineral oil; you will still have plenty of engine protection. The main values of synthetics are their ability to handle higher temperatures for longer periods without breaking down, and they keep combustion by products in suspension better for longer periods, but given that we control oil temp closely and change engine oil much more frequently than in automotive applications these attributes of synthetics are of little value to our engines. You will also save a lot of money!!! kind regards JGV ----- Original Message ----- From: Laurie Hoffman To: [email protected] Sent: Thursday, August 16, 2012 1:22 PM Subject: [DOG mailing list] Engine Oil
Hi All, I've been looking around for a Winter grade of engine oil for the Dimona. We have been using a Penrite semi synthetic. I went looking for a 15W-40 and I can find it only in full synthetic or straight mineral. I'm sure I read in the Limbach manual that full synthetic shouldn't be used. Any thoughts on going back to plain mineral? Regards Laurie Hoffman
