Okay, two of you have mentioned using synthetic oil (IMG:style_emoticons/default/ohmy.gif) I thought I was the only one who liked the stuff in an air-cooled engine (IMG:style_emoticons/default/wub.gif)

QUOTE(Air_Cooled_Nut @ Nov 27 2003, 09:17 AM) ... two of you have mentioned using synthetic oil I thought I was the only one who liked the stuff in an air-cooled engine why would you think this ? the only issue is that most of these air-cooled engines are -old- engines, many with unknown service histories (and oil leaks). synthetic can be a very efficient leak-finder... most of the T-IV's found in 914's are low-compression, low-revving engines used on the street. in this kind of service, especially if you're changing the oil every 3,000 mi anyway, it's hard to justify the additional expense. the 911E is a 9.1 compression engine i turn to 6500 rpm with some regularity. i was planning semi-annual oil changes but i just did it a 4th time since June. (and on not very many miles.) 9 quarts of Mobil-1 and a filter - the cost adds up... i do plan to keep this oil in there for a while tho ... |

ALL I use in my personal engines.......is synthetic oils!
Royal Purple and Valvoline all the way. Mobil 1 is for 911s, not TIVs. Tried it, dynoed it. |

QUOTE(Brad Roberts @ Nov 26 2003, 10:16 PM) Wait until we have a NorCal 914 club day when we go out to several JunkYards and BUY all of their T4 engines (for your use). We will send out "scoping" parties the weekend before and make a plan of attack with a open car trailer and my crew cab... should be fun. B What, like this?!!!

My 2002 Dodge pickup started rattling when I step on it, ever since the switch to winter ethanol gas at the pumps a week or so ago. The computer figures it out after a half second though and it stops rattling. Too bad the d-jet doesn't compensate for sh$t gas.

Because many people I talk with about synthetic in an air-cooled engine (let me specify...VW air-cooled engine) look at me like I attempted to fornicate with a goat in front of them. "They" say the engine will over-heat and leak like crazy blah blah blah. I have had neither problem and am a strong advocate of pure synthetic oil (IMG:style_emoticons/default/smile.gif) I've done my required reading (IMG:style_emoticons/default/cool.gif) However, I will tell ANYONE that if they stick to the standard oil change interval w/synthetic they are wasting their time and money. I double to triple the oil change interval. The filter, however, should still be changed per the manufacturer's recommendation. Like I said, I did my synthetic oil research. |

I have went over 10K miles in my 912E with the same oil (Royal Purple 20/50) I don't change it till I see it start to smoke between shifts. that means its gassed out and broken down.
I have been using synthetic in one Bus engine for 45K, went 2 solid years without an oil change. Just swap filters every 1500 miles. |
