I'm surprised it doesn't have marks all over it from the ten foot poles...

I have personally seen two batteries that were clearly declining, in spite of use of a battery tender several nights a week. (Granite Digital Save a Battery 50 watt) I switched to using a Battery Minder brand on both batteries with a sulfation cycle and both batteries over the course of several...

The only issue is you need a separate 12vt power source installed near the main battery. Will the charger allow both batteries to charge while driving? Is there any desulfation mode taking place? As I mentioned previously, desulfation seems more important than just maintaining state of...

No idea when or why. I suspect the spring that controlled the oil pressure changed value either from age or heat or something. I doubt they were shipped that way. You expect more from Ferrari? Lol...they are just cars like any other. And can have more issues because they don't make that...

Get one with a good desulfation mode as part of the algorithm. I'm finding this more important than just topping the battery off regularly with a battery tender. Battery Minder and Pulse Tech have good feedback here as actually working and my experience, at least with Battery Minder, backs...

All my 308 GTS photos are before I owned a digital camera...and I got my first camera just before I sold the 328 GTS...so very limited. I need to scan my pictures someday. I have a ton of pictures of the F355 Spider though...

Hardly "gutsy". High oil pressure were a known issue on some older Ferraris, that can get out of calibration. On most cars, which do not have an oil pressure gauge, how would you ever even know there is a high pressure issue? The idiot light only identifies low pressure. Carlo was a master...

The algorithm is different than the other Battery Minder products and BM will tell you that when you call tech support. It works though. I have used it with a bluetooth data logger to watch what it does. It can take a looooong time to reach float mode, I've observed up to 20+ hours on...

Usually the problem with engagement is the synchros...due to the fluid being too slippery...usually from additives for limited slip differentials. MTL does not have any slip additive, so it is popular for cars with shifting issues.

Agree with this completely. If the shop doesn't have references, just send it back to the factory.

Check your user manual. BM recommends you use the 2 amp mode for most situations. 4 amp for multi-battery charging and 8 amp for use with Odyssey batteries. Not absolutely sure of their rationale but probably following the typical adage "low and slow" is best for battery longevity when charging.

Just remembered another reason I went to using the Pennzoil 5w-40 euro oil. Not only was the oil pressure rather high while cold with the 15w-50, but it seemed rather high even when warm/hot. I ended up taking the car to my independent Ferrari specialist and he was able to adjust the oil...

Of course.

MTL is more synchro friendly (no slip lube for limited slip differential), so I can see where it could help with shifting. Don't hesitate to call the Redline tech support line, I have found them to be extremely knowledgeable and helpful.

Here's my 1987 328 GTS from back in the day (over 20 years ago!)...I loved that car...it had some great upgrades over the previous 308 series. More interior room, better AC, more power, better brakes. But retained those good looks, balanced handling, and great engine noise. Just a classic...

There are only two quality oil filters for this car, the factory approved UFI and the aftermarket Baldwin B253. The filter is mounted standing up, and has an internal standpipe and back flow valve. All other brands of filters that claim to cross reference either do not have a standpipe (Mobil 1...

Be sure to read the entire owners manual from cover to cover. There is some really good information in there. Not only maintenance and service info, but basics on how to properly use the heater and AC controls and checking the oil level and coolant levels.

My 2 cents: I am in a mild climate...I have been using battery tenders for over 15 years intermittently, but got more religious about it during the pandemic in 2020 due to my cars sitting more and now I use them constantly. My "fun" cars are constantly on battery tenders and daily drivers are...

I owned a 1978 308 GTS and later an 1987 328 GTS, both had similar recommendations in the manual to use AGIP 10w-50 and/or 10w-40 AGIP. Both were semi synthetic and of course, ancient formulations. In the late 1990s Ferrari recommended for most of their 80s and 90s era cars to use Shell...

My Toyota Tundra uses those blue sandwich oil plug washers. I hate them...at every oil change I have to pry or scrape that thing off. I bought a bag of 50 aluminum crush washers from Amazon for like $9 and never looked back.
