What kind of motor oil do you use?

At Mark S's suggestion, here's a poll on what kind of motor oil you use in your A4.

You may select as many choices as are relevant.

CalebD turned me onto the Shell Rotella SAE 30w - the P.O. used Mobil 1 in it for years and did not report any problem with slippage, etc..

I opted to go back to the dino juice, except I forgot to check it in the poll!

I wonder what distinguishes Penzoil's marine oil from its regular stuff (other than price, of course).

Exclamation Oil

I have been using for the last 26 years the same basic oil strategy. A good 30wt detergent motor oil~Chevron~Valvoline~Mobil~etc and I add a pint of STP oil treatment. I have a very steady oil pereassure 15~20 @ idle (700rpm) and 35~40 above 1300 up. I also use a bypass type of oil filter set up from Fram.
My lil beastie is now 40 years old and still ticking although I did do a valve job on her 26 years ago. The only thing not original are a few valve "keepers" and one exhaust valve.

Shell Rotella T 30w Label Change

I was wondering if there is a difference in the Shell Rotella T 30w and the Rotella T1 30w. The new label does not have the gasoline rating. It only shows CF-2 and CF. I have been using the Pennzoil 30w but looks like the Rotella might have better additives. Thoughts?

Smile read through this.

Hi, re your question in post #58:

It should be written on the bottle safe for gasoline engines as well. "S" rating should be there. If not, I don't know. The oil I buy states may be used in Gasoline, Diesel and Propane engines....attached is a read for you to look through. If you read more on the diesel aspect "C" and see what everything means and I think it's superior. Been running it for a long time now. Worth the read....enjoy.

Smile Oil Used

I'm using Shell Rotella T 1 30W.
Cduer, If you goggle "Shell Rotella engine oil" the Shell site has descriptions of all the Rotella oils including T & T1.
Regards, Bob P.

Question for the group.

How many of you have the old, manual oil extraction pump?

My 1966 has it. When I got the boat back from Harry, the yard removed it, threw it in the bilge. The leather cup was shot. I went to my auto part store on the advice of Ken. He sent me to the hardware store. Turns out a 1/2 inch faucet washer fits just fine.

Love that old pump. It's just cool. I put a two liter soda bottle in the bilge, and pump away.

Pre-season oil change done 10 April 2013. Used a drill pump to suck the old oil out but wasn't as happy with the results as when I used a shop vac. My son burned the motor out of it over the winter ...sucked plastic up around the air intake and burnt it up...so I'm down to one 5 gallon shop vac and have to keep that one hydrocarbon free..LOL.

I found the drill pump didn't have the ability to suck the base pan really dry...so, I may commission the "garage" shop vac for oil changes.

Mobile 15w40 in there again....change again in 20 - 25 hrs. Engine hrs on new meter showing 166. (I will refer to hrs here for next oil change as I have not started this year's log yet....I know I'll forget. ) Engine fired first thing again this year and purring like a kitty.

I love the 15-40w Rotella, too; but watch your start up pressure and let her warm up thoroughly before going to work.

I've been running the same 15-40w Rotella too, since day one (when I swapped out some kind of black treacle that the PO had apparently been using). Oil pressure hasn't been an issue, although I'm on Lake Ontario so only in the water April - Oct. I change the oil every 40h or so as it's cheap insurance, and it's always clean-looking when I change it.

Hanley, For this very reason (I was seeing 70+ PSI), I am trying the 5w-40 Synthetic Rotella for 2016. I'll let you know pressures after spring start up. Too bad we cannot change our poll choice as our decisions evolve.

Someone on here had good luck with Mobil 1 motorcycle oil. I am somewhat nervous about using automotive synthetics with a wet clutch.
BTW - our local Dollar Store has both Marvel Mystery Oil and Rotella 15w40

I switched from 10w30 to 15w40 Rotella for last season, after reading so many posts in favor of it.
I have noticed no significant change in pressure, but she does sound a little quieter.
I'm going to stick with it. I like the idea of more detergent.

With the 10w30, after motoring at idle speed for extended periods, when I would increase throttle, I would get a big puff of oil smoke. This seems to be greatly reduced (if not eliminated) with the heavier Rotella.

as a side note, I have used 5w30, 10w30, and straight weight 30.

I'm pretty sure lower viscosity yields higher pressure readings and more blow by and valve guide leakage, hence more smoke.
