I'm not convinced GL5 protects those parts.  I've been over in the other fun 45 page thread shaking the tree. Please come chime in, I didn't find anything convincing in the 45 pages I painstakingly read.

That's the plan. I was actually asking what additives I should use |

I used to use Delo 400 up until their formulation changed a couple years back (while the name remained the same).

Shoot.. of course they did. I was looking at Delo 400 due to the advice on Zinc content and how it was reported here that is key in our engines.
I live in California so oil doesn't need to do fine in the cold. The car has also been sitting for several years so if there are any additives to help clean out the build up for the first oil change or two I'd appreciate the advice.
What did you switch to? |

Any 15W-40 oil should have enough ZDDP for a stock engine. It's the 10W-30 and thinner grades marked API SM or SN and have the "API Certified" starburst symbol on the bottle that have questionably low amounts of ZDDP.

| I'm new to the VW community. Just bought my first dune buggy. It has a 74 beetle engine with a bus transmission. From the build sheet that came with it I gather it's 1800cc with a lot of scat parts. Reading through this post I see a lot of different opinions on oil types to use. Was wondering if anyone on here has a similar set up as me and could guide me in the right direction. Also since it has an external oil filter do I need to pull the lower access panel and replace/clean the internal oil screen? |

There are lots of oils that will work. Lots of guys here seem to prefer Valvoline VR1, Brad Penn or Amsoil Z-Rod, but many others will work. You might want to steer clear of the new SN or SM oils (with certified star burst symbol) that are 10W-30 or thinner. Any multi-grade oil that's 30, 40 or 50 could work although it would be easier to choose the right oil based on actual oil pressure. 15W-40 is mid-ground.

why? Didya read the label?
Reading the label it says a lot of stuff about resisting thermal breakdown, and good detergent, so it must be designed for hot running engines that the oil is changed rarely.
Yes the labels are usually 50% marketing language, but the other 50% might be true! |

| Whats the best oil to use in a stock 1600cc in the spring, summer and fall? |
That's nearly impossible to answer without knowing more about you and your engine. What is the climate like where you live? Is the engine fresh? Old and tired? Does it burn oil? How is the oil pressure (does the idiot light ever light up)?
I wouldn't hesitate to run 5W20 in a tight new engine (especially if it has a large oil pump), but older engines may need thicker stuff to maintain oil pressure. The engine in my '67 is fairly strong, but it's wearing out -- the blowby and oil consumption are increasing, and it needs 15W40 to keep the oil light out on 100°F+ days.
Good luck,
- Scott |
Good morning Scott. I have an old 1600 engine in my 73 beetle that the dummy light flickers on & off ocassionally. What oil type do you recommend. I live in Southern Cali. in the South Bay area. Temps are relatively cool here (about 5 -10 miles from the beach).
Thanks for any feedback! |

If it flickers on and off you might want to try a thicker oil. If you were using 10W-30 then use 15W-40. And if that doesn't do it then try 20W-50.
Of course an actual oil pressure gauge would be best. The rule of thumb is 10psi for every 1,000RPM. If you get more pressure than that, then go thinner. Less than that, then go thicker.

| I would say that putting a gauge on there and/or changing out the oil pressure switch would be the first steps to take. These switches do not last forever and yours may not even be the correct one for your application. |

What oil are you using now?
What is your idle speed? If you have it too low, the light will flicker. Increase it to meet VW's recommended idle speed and your flickering light may go away.

I have been using the Amsoil Z-Rod 10w30 for the past few years. I don't drive my car very much, but it seems fine. My car is a stock 1972 Karmann Ghia with a stock 1600. Sometimes at idle I will get a quick Flicker of the oil light, but I attribute that to a low idle caused by a carb in need of a rebuild.

|
|
Ok, I've read first 11 pages of this thread and the last two. The first 400 miles in my 71 camperbus's new engine has been with conventional Castrol 20-50 wt.
Summer is rapidly ending here in the St Louis Missouri area. I'm a little concerned about the Zinc factor. I think I'm going to go with Castrol Synthetic 20 - 50 wt and stick with that. Should I still add a half bottle of GM EOS if it still exists or skip it? |

Any 20W-50 should have enough ZDDP for a stock application. It's the 10W-30 and thinner grades that are restricted as to how much ZDDP. I would, however, avoid using the thickest oil possible on a new engine, unless the oil pressure says otherwise.
