A question for the masses: What motor oil are you using in your older classic? It's been a hot topic on just about every message board, and there seems to be equal parts confusion and passion.

Discuss.

My view on this is people obsess far too much about oil. If you change it frequently, I don't see what the big deal is as far as brand, synth vs dino, etc. My life has been much happier since I gave up worrying about it.

So, for the record, Castrol in everything. Mostly because it's available everywhere (Wally Mart too) and does seem to keep noisy lifters quieter longer than some other brands I've used.

Now filters...there I'll have a debate with you.

Yeah I agree with access hence my 2 picks.

I mean I could run the FIAT with Castrol all the time too, but the GT6 tappets require something more then Castrol offers. Good enough for the winter.

Filters. Generic for the winter storage, but K&N's for summer & racing.

Again with the FIAT I could just go generic and do a swap after every race weekend. $20 for 4.4L of 20w50 and a $4 for a Motormaster Filter.

I agree that the brand is less important than the cleanliness of the oil and filter. I typically use Mobil 1 in my cars but Castrol is the close second.

Curious, you say that Castrol seems to keep the lifters quiet, that would indicate that there IS a difference in the oils. Hmmm.

You caught that.

My Audi GT was notorious for lifter noise. Even with new lifters it was fussy. All oils would quiet them when fresh. Wally Mart generic 20-50 kept them quiet for about 1500 miles or a bit more, but would fail after a weekend of track duty. I tried Mobil 1 synth and it disappointingly was about as successful. And it leaked out of a new engine at some spots. Castrol consistently held up longer than anything else I tried and would keep things mostly quiet until about 2500 miles. End of track sessions were also quieter.

So, for the marginal difference in price per 5 qt at Wally Mart and it's ready availability, it's my simple and effective solution in most everything.

OTOH...our A2 VW Jetta GLI which lived on an exclusive diet of Castrol from 100,000 to about 170,000 wound up with a clogged oil pump screen (waxy substance). I fired Castrol for quite awhile after that, but alternative 'good' brands such as Pennzoil and Valvoline are just too hard to find around here without going to an expensive auto parts outlet.

I've been using Castrol 20W-50 in the Mini with ZDDP Plus. Usually not a fan of the various snake oil additives, but the zddp flat tappet issue made me think it was worth the peace of mind. No reason to tear up a nicely rebuilt (by Abacus Racing) engine.

I'm not sure if there is a topic that is more shrouded in mystery and superstition when it comes to cars than a discussion of motor oils.

Do you have to pay retail? That makes a big difference to most of us. Can't see spending that much on something I change as frequently as I do (should be changed seasonally regardless of miles driven).

Yeah cost is a factor the VR1 is 1/2 the price of Royal Purple.

I was testing the GT6 yesterday and in 9C outside she was only a 1/4 up on the temp gauge and no oil in the cool. (Stat is working)

The FIAT guys I know all live by the buy cheap and change often.

Boy, is that ever true. And typically it really raises tempers too. Over the years and on many different boards I always cringe when this topic comes up as it usually ends with much (cyber) yelling, name calling and some one getting banned. Guess we are all above that.
